Mayers Relation of specific heat

  1. May 23, 2006 #1
    Two expressions for relation between specific heats are given and it is asked to say which one is right. They are:
    1)Cp – Cv = R
    2)Cp – Cv = R/J
    Which of the 2 is right? Here Cp and Cv are the specific heat of gas at constant pressure and volume respectively. R is universal gas constant and J is the mechanical equivalent of heat.

    Both :smile: ...depends on what units you use.
