Questions
The molar heat capacity in a process of a diatomic gas if it does a work of when a heat of Q is supplied to it is
a
25R
b
52R
c
103R
d
67R
detailed solution
Correct option is C
dU = CvdT = (52R)dT or dT = 2(dU)5R------(i)From first law of thermodynamicsdU = dQ - dW = Q-Q4= 3Q4. Now molar heat capacity C = dQdT = Q2(dU)5R = 5RQ2(3Q4) = 103RTalk to our academic expert!
