Gas laws and absolute zero

Gas laws and absolute zero

Three graphs showing Boyle's law as a pressure-volume hyperbola, Charles's law as volume proportional to kelvin temperature, and the pressure law extrapolated to absolute zero at -273 °C Ideal gases connect the macroscopic variables pressure ppp, volume VVV, and temperature TTT. For a fixed mass of gas, each gas law keeps one variable constant and tells you how the other two change.

Step-by-step lessons on AQA A Level Physics Ideal gases (A-level only). Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
