Question

If Cp and C denote the
specific heats of nitrogen per
unit mass at constant
pressure and constant
volume respectively, then the
difference between them is
R/28
R/14
R/7
o
R/54

Answer 1

Answer:

R/28

Explanation:

It has to be known that , $C_{p}-C_{v}=R$ ; Where $C_{p} and C_{v}$ are specific heats per                                                

                                                                                                                      mole.

So, to convert per mole into per mass, $(C_{p}-C_{v})28=R$

       Therefore, the difference is R/28.
