Pressure in Gases
A series of free GCSE/IGCSE Physics Notes and Lessons.
Particle motion in gases
How particles move in gases and how this leads to gas pressure.
How the temperature of a gas is related to the kinetic energy of the particles?
How changing the temperature of a gas changes the pressure?
Pressure in gases
How particles collisions cause gas pressure?
Describe how the pressure of a gas is related to its volume.
Calculate changes in the pressure or volume of a gas.
Examples:
- A gas has a volume of 3 m3 and a pressure of 400 000 Pa. The volume is increased to 6 m3. Calculate the pressure.
- A gas has a volume of 10 m3 and a pressure of 50 000 Pa. The volume is increased to 50 m3. Calculate the pressure.
- A gas has a volume of 5 m3 and a pressure of 150 000 Pa. The pressure decreases to 50 000 Pa. Calculate the volume.
Work done on a gas
Describe the effect of doing work on an enclosed gas.
What is meant by work done?
How compressing a gas can increase its temperature?
