During the adiabatic expansion of 2 moles of a gas, the internal energy of the gas is found to decrease by 2 joules, the work done during the process on the gas will be equal to
Text Solution
Verified by ExpertsThe correct answer is:
D
$\mathrm{dQ} = 0 = -2 + \mathrm{dW} \Rightarrow \mathrm{dW} = 2 \, \mathrm{J}$
$\Rightarrow$ Work done by the gas = 2 J
$\Rightarrow$ Work done on the gas = -2 J
