From Ist law of thermodynamics d Q=d U+d W From adiabatic process d Q=0 ∴ d W =-d U=-(-50) =50 J

Q. During an adiabatic expansion of $2$ mole of gas, the change in internal energy was, found - $50 J$ . The work done during the process:

50 J

-50 J

100 J

From Ist law of thermodynamics $d Q = d U + d W$
From adiabatic process $d Q = 0$
$∴ d W = - d U = - (- 50)$
$= 50 J$
