ideal gas: gas that obeys exactly KEY IDEAS Gases are the least dense of the three phases of matter. The molecules in a gas are much farther apart than are molecules in liquids or solids. A gas moves about freely, has no definite shape or volume, and spreads out to fill a closed container of any size. Respiratory therapists and paramedics use oxygen gas when they wor with patients. The air you breathe is about 20 percent oxygen. It is als about 79 percent nitrogen, which you cannot use. In an emergency or if yc are ill, you may be given additional oxygen to breathe. Kinetic Theory. The kinetic theory (kih-NEHT-ick THEE-uh-re describes gases. The ideas of this theory help explain the properties ar behavior of gases. The main parts of the theory are as follows: Hitert 1. Gases are made of very small molecules. 2. Gas molecules are far apart. Most of the volume of a gas is emp space. 3. Gas molecules do not repel or attract each other. Gas molecules are always moving. As they move, they bump into ea 4. other and the walls of any container they are in. DE of gas molecul 5.
