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
