Macroscopic and microscopic views
Kinetic theory links the measurable properties of a gas, pressure ppp, volume VVV, temperature TTT, and amount nnn, to the motion of its molecules. For an ideal gas, the same state can be written as pV=nRTpV = nRTpV=nRT or pV=NkTpV = NkTpV=NkT.
Step-by-step lessons on Eduqas A Level Physics Kinetic Theory. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- a minimum of 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.
