- Homework Statement
- Cp and Cv are specific heats at constant pressure and constant volume respectively. It is observed that
Cp−Cv =a for hydrogen gas
C p−Cv=b for nitrogen gas
The correct relation between a and b is :
- Relevant Equations
- Cp-Cv=R where R is gas constant
According to me a=b cause what I have been learning is R is gas constant and hence it will be same for both. But the solution have says something else.
According to them Cp-Cv=R/M where M is the molecular mass of gas.
So is the above mentioned formula correct? Do we have to take that M term always and in all the problems?
