One mole of an ideal gas is taken from A to B , from B to C and then back to A . The variation of its volume with the temperature for that change is as shown . Its pressure at A is `P_(0)` , volume is `V_(0)` . Then , the internal energy .

Options

A. at A is more than at B
B. at C is less than at B
C. at B is more than A
D. at A and B are equal

Answer

D

Explanation

The internal energy of an ideal gas is only dependent upon its temperature . From the graph , The ideal gas at same temperature at A and B .
`therefore` The internal at energy A and B are equal or `U_(A) = U_(B)`
