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

The correct option is C of $B$ will be more than that of $A$

of B will be more than that of A.

There will be no change in the internal energy of the ideal gas.

But for the real gas, the increase in internal energy takes place

because of the work done against the intermolecular forces.
