Matter is anything that physically takes up space and has mass. More specifically, anything that is made up of atoms is considered matter, which is everything.
Matter is made of single particles called atoms and is any substance that has either mass or volume. Matter can exist in three states, either as a solid, a liquid or a gas.
Matter changes via two processes: a physical change or a chemical change. Physical changes retain the fundamental identity of a substance without modifying its composition, while chemical changes alter matter into another form having a set of different properties from t...
Organic matter is composed of the remains of animals and plants and the waste products the organisms leave in the environment. Unlike organic material, organic matter has decomposed to the point that it is resistant to decomposition. This matter is decomposed into a hum...
Air is composed of matter. Air is gas, so it is composed of molecules that are spread far apart from each other.
All physical objects, such as stars, books, people, animals, plants and the sea, are examples of matter. Matter is any physical object that occupies space and has mass.
The three states of matter are solid, liquid and gas. Each state of matter is defined by physical characteristics such as its shape, volume and compressibility. Changing from one state of matter into another is accomplished by altering the temperature, pressure or compo...
