The figure shows the change in a thermodynamic system is going from an initial state A to the state B and C and returning to the state A. if UA = 0, UB = 30J an the heat given to the system in the process B → C, 50J, then determine:
(i) internal energy in the state C
(ii) heat given to the system in the process A B
  • a)
    80J, 90J
  • b)
    120J, 60J 
  • c)
    90J, 80J
  • d)
    50J, 60J

Work done in the process B → C, W = 0 
Volume is constant and heat given to the system 
Q = 50J (given) 
Hence, by the first law of thermodynamics, the change in the internal energy is 
ΔU = (UC - UB) =  Q - W = 50J 
UC = UB + ΔU = 30 + 50 = 80J 
(ii)  For the process A → B, ΔU = UB - U
= 30Joule and W = area ABCD = DE × DA 
= 2 × 30 = 60J 
∴ Q = ΔU + W  = 30 + 60 = 90J
