If ' Q^ is the amount of heat supplied to 'n' moles of a diatonic gas at constant pressure, ' U ^ is the change in internal energy and ' W ^ is the work done, then W : U : Q is
Options
- A2: 3: 4
- B1: 2: 3
- C2: 5: 7
- D5: 7: 9
Correct answer
C. 2: 5: 7
Step-by-step solution
We know, array l Q = nC _ p T U = nC _ v T W = P V = nR T W : U : Q = R : C _ v : C _ p array For a diatomic gas f=5 aligned & C_ v = f 2 R= 5 2 R & C_ p =C_ v +R= 7 2 R R: C_ v : C_ p =1: 5 2 : 7 2 =2: 5: 7 aligned
