Hello to everyone!(adsbygoogle = window.adsbygoogle || []).push({});

This is my first time that I use forums and I hope you will help me!

Here is my question/problem:

Is it possible using the second thermodynamic law to proove that:

If the total work done by heat engine operated between two temperatures is zero,

than it follows that the total heat absorbed by the system is greater than zero.

I am sure I saw this somewhere but unfortunately I cannot found it :(

Thank you in advance!
