(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The problem is as following:

2. Relevant equations

[itex]\Delta[/itex] E = [itex]\Delta[/itex] Q-[itex]\Delta[/itex] W

3. The attempt at a solution

Now I know that if work is done by the system then work sign is negative and that if volume remains unchanged then no work is done.

Am I right to say that Internal energy @ C is 50 joules ?

How does that answer my question ? I know over all energy is conserved in cycle.

Any tips please.

Edit i see that the screenshot hasnt loaded i will edir it once i get back home

Thanks!
