Quick questions on Ideal gases: the gas laws and kinetic theory - WJEC A-Level Physics

3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.

What is kinetic theory?

Show answer

The kinetic model assumes many identical molecules in random motion, of negligible volume, making perfectly elastic collisions with no intermolecular forces between collisions. The derivation gives:

What is q1?

Show answer

A gas of

0.20\,\text{mol}

occupies

5.0\times10^{-3}\,\text{m}^3

300\,\text{K}

. Find its pressure. Take

R = 8.31\,\text{J mol}^{-1}\text{K}^{-1}

What is q2?

Show answer

State how the mean kinetic energy of a gas molecule depends on temperature. [1 mark]
