Q. For the isothermal expansion of an ideal gas
A) $E$ and $H$ increases
B) $E$ increases but $H$ decreases
C) $H$ increases but $E$ decreases
D) $E$ and $H$ are unaltered
Explanation
(d)
In isothermal reversible process, ideal gas has constant volume and so, $\mathrm{\Delta}E = 0$ and $\mathrm{\Delta}H = \mathrm{\Delta}E = 0$
