Laws of Thermodynamics
Zeroth Law
If A and B are in thermal equilibrium with C, then A and B are in equilibrium with each other.
First Law
Energy is conserved: ΔU = Q - W. Heat added equals work done plus change in internal energy.
Second Law
Entropy of an isolated system never decreases. Heat flows from hot to cold spontaneously.
Third Law
Entropy approaches zero as temperature approaches absolute zero.
