-We previously introduced the [[phy141:​lectures:​35&#​specific_heat_capacity|specific heat]] which gives the [[wp>​Heat_capacity|heat capacity]] heat capacity of a material per unit mass. Here we will use molar specific heats for gases at constant pressure $c_{P,m}$ and constant volume $c_{V,m}$ and explain the difference between these on the basis of the first law of thermodynamics.+We previously introduced the specific heat which gives the [[wp>​Heat_capacity|heat capacity]] heat capacity of a material per unit mass.

 If we increase the temperature of a gas by $\Delta T$ at constant volume $Q_{V}$ then the first law tells us that  If we increase the temperature of a gas by $\Delta T$ at constant volume $Q_{V}$ then the first law tells us that
