Physics: Thermal & Matter

Topic overview

Specific heat capacity, latent heat and changes of state, heat transfer, density and pressure, the particle model of gases (official P4/P5)

Key concepts

The five modules are verified separately. Math 1 contains no calculus; Math 2 does not require complex numbers, matrices or general differential equations. Each combination reuses module questions and shares them with the special-topic practice; it is for scope-restricted training only and does not represent unseen questions, complete coverage or official difficulty. Please choose modules according to the course you are applying for.

Key points

◆Follow the prerequisite knowledge requirements given by the examination body; new concepts may only be used when the question provides sufficient guidance.
◆The examples on this site are training with a limited scope and do not represent full syllabus coverage or official difficulty.

Worked examples

Try each example yourself before checking the explanation.

1Basic examples within scope
