Q 1649645513.     One mole of an ideal gas in initial state A undergoes a cyclic process ABCA, as shown in the figure. Its pressure at A is `P_{0}`. Choose the correct option(s) from the following

JEE 2010 ADVANCED Paper 1

(This question may have multiple correct answers)

A Internal energies at A and B are the same
B Work done by the gas in process AB is `P_{0}V_{0}ln4`
C Pressure at C is `\frac{P_{0}}{4}`
D Temperature at C is `frac{T_{0}}{4}`

HINT

Since the temperature is constant in process AB, it is isothermic process and hence no change in internal energy. `(\Delta U=0)`
