Change in internal energy: Really Big or Really Small

Postby Natalie Yakobian » Sat Jan 09, 2016 11:05 am

Hi,
I was wondering if you have a really large negative change in interal energy and a smaller negative change in internal energy which one would be considered greater?

It seems to me that the negative sign just tells us whether energy is used or gained so the negative sign doesn't matter in terms of size, but I'm not sure.

Thanks so much.

When solving for change in internal energy, a negative sign indicates that energy is lost by the system. A system with a large negative change in internal energy loses a greater amount of energy then a system with a small negative change in internal energy.
