Question

when an ideal diatomic gas is heated at const pressure then the fraction of heat energy used to increase the internal energy of gas system is ?

Answer 1

When an ideal diatomic gas is heated at constant pressure then the fraction of heat energy which is used to increase the internal energy of the system is

Answer 2

f= (ΔU/ΔQ)=(nCvΔT)/(nCpΔT) = (Cv/Cp) =1/g

or f=5/7

(as g = 7/5)
