Asystem undergoes a two-step process. in the first step, the internal energy of the system increases by 222 j when 150 j of work is done on the system. in the second step, the internal energy of the system increases by 123 j when 195 j of work is done on the system. for the overall process, find the heat.

0 J

Explanation:

Given

For first step

change in internal Energy of the system is

Work done on the system

For second step

change in internal Energy of the system is

Work done on the system

Work done on the system is considered as Positive and vice-versa.

and from first law of thermodynamics

for first step

overall heat added

For overall Process Heat added is 0 J

the answer would be a
