Question

An ideal gas A and a real gas B have their volumes
increased from V to 2V under isothermal
conditions. The increase in internal energy
(a) will be same in both A and B
(b) will be zero in both the gases
(c) of B will be more than that of A
(d) of A will be more than that of B

Answer 1

Since A is an ideal gas, no change in internal energy takes place for A but change in internal energy takes place for B since it is a real gas. Hence change in internal energy of B will be more than that of A.

Thus (c) is the answer.

Answer 2

Answer:

B is more than A,,, option C

Explanation:

It assumes that in case of ideal gas there is no force of attraction between gas molecules.....so change in internal energy....it is opposite for the real gas
