CIE-Review-Thermodynamics Cheat Sheet (DRAFT) by

my reviewer for thermodynamics in preparation for the CIE examination go IEs

This is a draft cheat sheet. It is a work in progress and is not finished yet.


The science that studies the relati­onship of heat with other forms of energy.

Laws of Thermo­dyn­amics

Zeroth Law
Thermal equili­brium is transi­tive.
If A=B, B=C, then A=C
1st Law
Energy cannot be created or destroyed; it can only be converted from one form to another, or conserved.
ΔU = Q - W
2nd Law
Entropy of an isolated system always increases. Heat always moves from hotter objects to colder objects, unless energy in some form is supplied to reverse the direction of heat flow
3rd Law
