Question

a system udergoes a process consisting of the following 2 steps-
1. absorbs 79J of heat while 26J of work is done to it
2. system absorbs 26J of heat while preforming 79J of work

what is overall ÄE?

is it 52J?

Answer 1

I think you are correct but get a second opinion.

Answer 2

Step 1: Change in E2 = q+w ; 79+26=105J

Step 2: Change in E2 = 26-79=-53J

Change in E overall = Change in E1 + Change in E2 ; 105-53=52J

So yes, you are correct.
