Different factors affect the behavior of gas

3. Describing Gas Behavior
The space that gas particles occupy is the gas’s volume. Volume can change as temperature and pressure cange.
The temperature of the gas is determined by the amount of particle movement. The faster the particle movement, the greater the temperature.
The more the particles move, the more they try to move away from each other. This causes them to run into the sides of the container holding the gas.
Describing Gas Behavior

4. Describing Gas Behavior
The force the particles exert on the sides of the container is known as pressure.
Pressure is the amount of force exerted on a given area of a surface.
The more particles that hit the sides of the container the greater the pressure.
The volume of a gas changes depending on the volume of the container holding it.

5. The temperature, pressure, and volume of a gas are related to each other. Consequently, if you change on factor, the others are also affected.
Boyle’s Law states that for a fixed amount of gas at a constant temperature, the volume of the gas is inversely related to the pressure. Example: volume increases, pressure decreases
Charles’ Law states that for a fixed amount of gas at a constant pressure, as the volume changes then the temperature will change in the same way. Example: volume increases, temperature increases
Gay-Lussac’s Law states that for a fixed amount of gas at a constant volume as the temperature changes the pressure changes in the same way. Example: Pressure Increase, Temperature Increases
