Topic overview

Scope-restricted training: gases, heat, changes of state and heat transfer; unverified university-level prerequisite methods such as the Carnot cycle do not enter the new question sets.

Key concepts

Round 1/2 cannot be mixed. This site only provides training with limited scope; unverified university-level methods do not enter new problem sets, and no claim is made to be an official complete paper.

Key points

◆Follow the prerequisite knowledge requirements given by the examination body; new concepts may only be used when the question provides sufficient guidance.
