50\,{}^{\circ}\text{C}

to kelvin. [1 mark]

What is q2?

Show answer

A gas at

200 \text{ kPa}

and

0.30 \text{ m}^3

is compressed at constant temperature to

0.10 \text{ m}^3

. Find the new pressure. [2 marks]

What is q3?

Show answer

Use the kinetic model to explain why heating a gas at constant volume raises its pressure. [2 marks]
