An ideal gas is made to go through a cyclic thermodynamical process in four steps. The amount of heat involved are

{Q_1} = 600J,{Q_2} = - 400J,{Q_3} = - 300J

and

{Q_4}

=200 J respectively. The corresponding work involved are

{W_1} = 300J,{W_2} = - 200J,{W_3} = - 150J

and

{W_4}

. What is the value of

{W_4}

View answer and explanation

Correct option: C

150J

Option C (150 J) is correct because it applies the first law of thermodynamics for a cyclic process, where the net heat equals the net work done.
