Question

In an adiabatic expansion of ideal gas

A

$W = - \Delta U$

B

$W = \Delta U$

C

$\Delta U = 0$

D

$W = 0$

Answer

$W = \Delta U$

Explanation

Solution

Since the system is insulated, heat is not allowed to enter or leave the system. Thus, $q = 0$ , $\Delta U = q + W$ $\Rightarrow \Delta U = W$
