Physics: Year 9 Term 4: Gas Pressure, Temperature and Volume

What is pressure caused by? (1)
Impacts of atoms against the insides of a container
1 of 7
Increasing temperature does what to pressure and why? (2)
Increases as particles move faster
2 of 7
Brownian motion is explained how by particle movement? (2)
The random motion of small gas particles buffets the larger particles
3 of 7
The force of pressure is at what angles to the container walls? (1)
Right angles
4 of 7
Increasing volume does what to pressure and why? (2)
Decreases as there is the same amount of gas spread out in larger space
5 of 7
What is Boyle's law? (2)
Pressure x volume in a gas = a constant
6 of 7
If quickly pressurised why does the temperature increase? (2)
Work is done on it and the energy not transferred to the surroundings quickly enough
