What is Delta E?

Postby Glenda Marshall DIS 3M » Tue Jan 20, 2015 8:18 pm

In homework problem number 15, it says that delta E is zero. What is delta E and how does that help us determine work?

In this question, deltaE is the change in energy. In both cases, since the temperature is constant the change in energy is 0, it is just the work and heat that fluctuate in charges.

correct me if I'm wrong but I'm pretty sure Delta E has the same formulas as delta U which is q+w

Yes, delta E and delta U are used interchangeably. It just depends on the book and personal preference.
