JEE Advanced2010PhysicsThermodynamicsActual
One mole of an ideal gas in initial state A undergoes a cyclic process A B C A , as shown in the figure. Its pressure at A is p₀ . Choose the correct option(s) from the following
Options
- AInternal energies at A and B are the same
- BWork done by the gas in process A B is p₀ V₀ 4
- CPressure at C is p₀ 4
- DTemperature at C is T₀ 4
Correct answer
A. Internal energies at A and B are the same
Step-by-step solution
aligned & T_A=T_B U_A=U_B & W_ A B =(1)(R) T₀ ( V_f V_i ) & =R T₀ ( 4 V₀ V₀ ) & =p₀ V₀ (4) aligned Information regarding p and T at C can not be obtained from the given graph. Unless it is mentioned that line B C passes through origin or not. Hence, the correct options are (a) and (b).
