Two different equations

Postby Adam Kramer 1A » Sun Feb 02, 2020 6:17 pm

Can someone explain the difference between the two work equations and when we would use each one?

The first work equation is the one with the integral and you would use that if pressure isn't constant. However, if pressure is constant then you would use w = -P ΔV.

The difference between the two work equations is that one includes the integral and one does not. You use the work equation without the integral when pressure is constant.
