9/20/2010 ME200 Therm I Lecture 12, Prof. Mongia 2 Specific heat is the energy required to raise the temperature of a unit mass of a pure substance by one degree In thermodynamics, we consider two important specific heats Constant volume specific heat : describes change in temperature for process with no p d v work (constant volume) Constant pressure specific heat : describes change in temperature for process with p d v work included Specific Heat at Constant Volume , - c v is related to change in internal energy per unit change in temperature at constant volume
