Unformatted text preview: The relation between Cp and CI,- If something is heated at constant p we generally observe an expansion. So the system receives energy in the form of heat but loses energy in the form of p Vwork. Therefore the temp. rises less than when heating at constant v olume. The rate of change of temp. wrt. heat. is less at constant p than at constant V. Recall that C is a measure of the rate of change of the systems heat w.r.t. temperature. 02a 61' So, if the temp. of a system rises slower at constantp compared to constant V, then it follows that: Cp > C V ...
