When To Use Cv Or Cp. When a heating or cooling process is carried out with no change in volume Cv is used. Can someone please explain when we use Cv and when we use Cp and how we would know which one to use?
Specific heats or molar heats of gases-. ' The specific heat of a substance is the quantity of heat required to raise the temperature of one gram of " While when the gas is heated at constant pressure the heat is used in increasing the kinetic energy of the molecules and some work is done. Cp is greater than the molar specific heat at constant volume Cv because energy must now be supplied not only to raise the temperature of the gas but also for the gas to do work.

As the name implies, Cp is referred to sp heat at constant pressure.
Online calculator, figures and tables showing how specific heat (Cp and Cv) of dry air vary with temperature at different pressures, SI and imperial units.
Result. _ So we get that Cp > Cv. A modification in our process demands to create a warmth exchanger intended for heating nitrogen gas to My spouse and i am uncertain about the specific heat by constant volume (Cv).
