Pressure of gases

• Colliding gas particles creates pressure.
• Changing the temperature changes the pressure.
• A sealed container is an example of a closed system - no matter can get in or out.
• Since the particles themselves hardly take up any space, most of the gas is empty space.
• The volume decreases so expect the pressure to increase.
• The warmer something is the more particles move.
• Gas particles move randomly and bang into anything that gets in the way, like the walls of their container.
• When gas particles collide they exert a force on what they collide with.
• The more particles there are given in the volume the more they will collide.
• The pressure gases exert depends on their speed.
• Pressure (Pa) x Volume (m^3) = Constant
