A 5-step lesson. Step 1: 'Zeroth Law: If A is in thermal equilibrium with B, and B with C, then A is in equilibrium with C. (This is why thermometers work!)' Step 2: 'First Law: ΔU = Q - W. The change in internal energy of a system equals heat added minus work done BY the system. This is conservatio
