Powerpoint lecture covering the following in a modern, concise format:

Specification Point 5.15 - Explain how molecules in a gas have random motion and that they exert a force and hence a pressure on the walls of a container.

Specification Point 5.16 - Understand why there is an absolute zero of temperature which is –273 °C.

Specification Point 5.17 - Describe the Kelvin scale of temperature and be able to convert between the Kelvin and Celsius scales.

Specification Point 5.18 - Understand why an increase in temperature results in an increase in the average speed of gas molecules.

Specification Point 5.19 - Know that the Kelvin temperature of a gas is proportional to the average kinetic energy of its molecules.

Specification Point 5.20 - Explain, for a fixed amount of gas, the qualitative relationship between: pressure and volume at constant temperature, pressure and Kelvin temperature at constant volume.

Specification Point 5.21 - Use the relationship between the pressure and Kelvin temperature of a fixed mass of gas at constant volume.

Specification Point 5.22 - Use the relationship between the pressure and volume of a fixed mass of gas at constant temperature.
