What do you call fine particles?
The term fine particles, or particulate matter 2.5 (PM2.5), refers to tiny particles or droplets in the air that are two and one half microns or less in width. Like inches, meters and miles, a micron is a unit of measurement for distance.
What is an extremely small piece of matter?
Explain that all matter on Earth exists in the form of a solid, liquid, or gas, and that solids, liquids, and gases are all made of extremely tiny particles called atoms and molecules. Tell students that an atom is the smallest building block of matter and a molecule is two or more atoms connected together.
What does the term fine particle fraction mean?
The fine particle fraction (FPF) represents the mass percentage of drug particles with an aerodynamic diameter below 5 μm, and is used for in vitro assessment of the aerodynamic properties of aerosols.
How can we reduce particulate matter?
Avoid high-traffic roads, such as highways. Avoid unnecessary idling of vehicles, especially in enclosed spaces, like a garage. Reduce time spent outdoors during times with high pollution. Consider purchasing electric vehicles.
What do you call a very small particle?
OTHER WORDS FOR particle
1 mite, whit, iota, jot, tittle, grain, speck.
What are the characteristics of the particles of matter?
- They have spaces between them.
- The particles of matter are continuously moving.
- The particles of matter attract each other.
- Particles of matter are very tiny in size which can exist independently.
Is not made of matter?
Non-matter includes the light from a torch, the heat from a fire, and the sound of a police siren. You cannot hold, taste, or smell these things. They are not types of matter, but forms of energy. Everything that exists can be classed as either a type of matter or a form of energy.
What are solid particulates?
Particulate matter is the sum of all solid and liquid particles suspended in air many of which are hazardous. This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets. These particles vary greatly in size, composition, and origin.
What is the particle size of fine sand?
Sand is commonly divided into five sub-categories based on size: very fine sand (1/16 – 1/8 mm), fine sand (1/8 mm – 1/4 mm), medium sand (1/4 mm – 1/2 mm), coarse sand (1/2 mm – 1 mm), and very coarse sand (1 mm – 2 mm). These sizes are based on the Φ sediment size scale, where size in Φ = -log base 2 of size in mm.
Where do ultrafine particles come from?
Ultrafine particles are most commonly emitted through combustion from natural or human sources. Human activity is believed to be responsible for the largest share of UFPs due to the prevalence of UFPs in cities, where global industrialization and population growth have had the most notable impact on air pollution.
What causes fine particle pollution?
Primary sources cause particle pollution on their own. For example, wood stoves and forest fires are primary sources. Secondary sources let off gases that can form particles. Power plants and coal fires are examples of secondary sources.

Fine Particles (PM 2.5) Questions and Answers
Fine Particles (PM 2.5) Questions and Answers
Fine particulate matter (PM 2.5 ) is an air pollutant that is a concern for people’s health when levels in air are high. PM 2.5 are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated. Outdoor PM 2.5 levels are most likely to be elevated on days with little or no wind or air mixing. The New York State Departments of Health (DOH) and Environmental Conservation (DEC) alert the public by issuing a PM 2.5 Health Advisory when PM 2.5 concentrations in outdoor air are expected to be unhealthy for sensitive groups.
What is Particulate Matter 2.5 (PM 2.5 )?
The term fine particles, or particulate matter 2.5 (PM 2.5 ), refers to tiny particles or droplets in the air that are two and one half microns or less in width. Like inches, meters and miles, a micron is a unit of measurement for distance. There are about 25,000 microns in an inch. The widths of the larger particles in the PM 2.5 size range would be about thirty times smaller than that of a human hair. The smaller particles are so small that several thousand of them could fit on the period at the end of this sentence.
How can PM 2.5 affect my health?
Particles in the PM 2.5 size range are able to travel deeply into the respiratory tract, reaching the lungs. Exposure to fine particles can cause short-term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath. Exposure to fine particles can also affect lung function and worsen medical conditions such as asthma and heart disease. Scientific studies have linked increases in daily PM 2.5 exposure with increased respiratory and cardiovascular hospital admissions, emergency department visits and deaths. Studies also suggest that long term exposure to fine particulate matter may be associated with increased rates of chronic bronchitis, reduced lung function and increased mortality from lung cancer and heart disease. People with breathing and heart problems, children and the elderly may be particularly sensitive to PM 2.5 .
Where does PM 2.5 come from?
There are outdoor and indoor sources of fine particles. Outside, fine particles primarily come from car, truck, bus and off-road vehicle (e.g., construction equipment, snowmobile, locomotive) exhausts, other operations that involve the burning of fuels such as wood, heating oil or coal and natural sources such as forest and grass fires. Fine particles also form from the reaction of gases or droplets in the atmosphere from sources such as power plants. These chemical reactions can occur miles from the original source of the emissions. In New York State, some of the fine particles measured in the air are carried by wind from out-of-state sources. Because fine particles can be carried long distances from their source, events such as wildfires or volcanic eruptions can raise fine particle concentrations hundreds of miles from the event.
PM 2.5 is also produced by common indoor activities. Some indoor sources of fine particles are tobacco smoke, cooking (e.g., frying, sautéing, and broiling), burning candles or oil lamps, and operating fireplaces and fuel-burning space heaters (e.g., kerosene heaters).
Is there an air quality standard for PM 2.5 in outdoor air?
Yes, the United States Environmental Protection Agency (EPA) established National Ambient Air Quality Standards for PM 2.5 in 1997 and revised them in 2006 and 2012. National Ambient Air Standards are established to be protective of public health. The short-term standard (24-hour or daily average) is 35 micrograms per cubic meter of air (µg/m3) and the long-term standard (annual average) is 12 µg/m3. A microgram is a unit of weight. There are a million micrograms in a gram, and a pound is equal to about 450 grams.
How will I know when PM 2.5 levels are, or will be, elevated outside?
Outdoor air levels of fine particles increase during periods of stagnant air (very little wind and air mixing), when the particles are not carried away by wind, or when winds bring polluted air into the state from sources outside the state. In general, as the levels of PM 2.5 in outdoor air increase, the air appears hazy and visibility is reduced. These conditions are similar in appearance to high humidity or fog. The New York State Department Environmental Conservation informs the public whenever fine particle concentrations in outdoor air are expected to be elevated. Every weekday morning the Department of Environmental Conservation will review weather conditions and data from their air monitoring stations to determine if, for that day or the following day, fine particle levels are expected to exceed levels considered unhealthy for sensitive groups. If it is likely that this level will be exceeded, the agency will contact the media so that a Particulate Matter Health Advisory can be carried on afternoon and evening broadcasts. The Department of Environmental Conservation also provides PM 2.5 monitoring data and PM 2.5 forecasts on its web site.
Are there ways to reduce my exposure to PM 2.5 ?
When outdoor levels of PM 2.5 are elevated, going indoors may reduce your exposure, although some outdoor particles will come indoors. If there are significant indoor sources of PM 2.5 , levels inside may not be lower than outside. Some ways to reduce exposure are to limit indoor and outdoor activities that produce fine particles (for example, burning candles indoors or open burning outdoors) and avoid strenuous activity in areas where fine particle levels are high.
Who can I contact if I have more questions?
Matter Is Made of Tiny Particles
Objective
Students will develop a model to describe that matter is made up of tiny particles, too small to be seen. Students will use the model to describe the differences in attraction among the particles of a solid, liquid, and gas. Finally, students will use their models of solids, liquids, and gases to explain their observations in the lesson.
Key Concepts
Matter on Earth is in the form of solid, liquid, or gas.
Solids, liquids, and gases are made of tiny particles called atoms and molecules .
and . In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don’t move past one another.
In a liquid, the particles are attracted to each other but not as much as they are in a solid. The particles of a liquid are close together, always moving, and can slide past one another.
In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. The particles don’t interact with one another but just hit and bounce off of each other when they collide.
NGSS Alignment
NGSS 5-PS1-1: Develop a model to describe that matter is made of particles too small to be seen.
Summary
Students are introduced to the idea that matter is made up of tiny particles called atoms and molecules.
Students observe a solid metal hammer and a nail and view a molecular model animation of the particles in a solid.
Students squeeze a flexible plastic bottle with a balloon on top of the bottle to develop a model of the particles of a gas.
Students also try to squeeze a bottle filled with water to develop a model of the particles of a liquid.
Students watch a short animation that illustrates the incredibly tiny size of atoms and molecules.
Finally, students make an argument that even though a mound of shaving cream keeps its shape, it is not a solid, and that even though sand takes the shape of its container, it is not a liquid.
Evaluation
Print the student activity sheet and distribute one per student when specified in the activity. The activity sheet will serve as the Evaluate component of the 5-E lesson plan.
Safety
Make sure you and your students wear properly fitting safety glasses or goggles.
Clean-up and Disposal
Remind students to wash their hands after completing the activities.
Save the bottles and sand for future use. All other common household or classroom materials can be saved or disposed of in the usual manner.
Materials
Materials for the Demonstration
Hammer, nail, and wood
Materials for Each Group
Flexible plastic soda bottle (18-20 oz.) with cap
Balloon
Note: Flexible plastic soda bottles work better than disposable water bottles because water bottles are often not very flexible and tend to crush completely when squeezed.
Materials for the EXTRA EXTEND Demonstration
