Gas Pressure
What you need to know
Explain that molecules within a gas are in a state of constant random motion.
Relate the temperature of a gas to the average kinetic energy of its molecules, understanding that higher temperatures correspond to greater kinetic energy and faster average molecular speeds.
Describe how the collisions of gas molecules with the walls of their container exert a force, resulting in gas pressure.
Explain the qualitative relationship between the temperature and pressure of a gas held at a constant volume, noting that pressure changes as temperature changes.
