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

The First Law of Thermo­dyn­amics

∆(Energy of the System) + ∆(Energy of the Surrou­ndings) = 0

Internal Energy, U

Change in Internal Energy

Absorbs heat, Work to Surrou­ndings
∆E = Q - W
Cyclic Process
∆E = 0
Adiabatic Process
W = -∆E ; Q = 0
Change in Internal Energy
∆U = Q + W

PV-Work System

dW = F x dx
P = F / A
dW = P A dx
dV = A dx
dW = P A (dV/A)
W = P dV
Wig = -P (V2-V1)
Wig = nrt (In V1/V2)
