9.3 Pressure in Gases

This section covers the following syllabus (Physics 5059) requirements.

• explain the pressure of a gas in terms of the motion of its molecules
• recall and explain the following relationships using the kinetic model (stating of the corresponding gas laws is not required):

(i)    a change in pressure of a fixed mass of gas at constant volume is caused by a change in temperature of the gas

(ii)   a change in volume occupied by a fixed mass of gas at constant pressure is caused by a change in temperature of the gas

(iii)  a change in pressure of a fixed mass of gas at constant temperature is caused by a change in volume of the gas
