In an adiabatic expansion of ideal gas:

a
W=-ΔE
b
W=E
c
E=0
d
W=0

detailed solution

Correct option is B

In an adiabatic expansion the heat is not exchanged by the system with the surrounding. The work done in an adiabatic expansion of ideal gas is zero.

So, E=q+w

=>E=0+W=W

Hence, In an adiabatic expansion of ideal gas W=E.

Therefore, option (B) is correct.
