Description
Calorimetry, Heat Capacity, and Thermodynamics At constant volume, ΔU = q v Heat q iv a direct measure of internal energy qv= nC ΔTv At constant pressure, ΔU = q -PΔVP 1. in liquids and gases, change is close to 0, so ΔU = q P 2. if ΔU = q , then q = q P P v • qP=ΔU + PΔV • when P is constant, P ΔV = ΔPV 1. q P ΔCU + PV
