Pressure and Volume in a Bomb Calorimeter

Postby Mary Becerra 2D » Sat Mar 17, 2018 4:52 pm

In a calorimeter, since w = -PdeltaV and deltaV=0 and w=0 does that mean that P=0. Or does that imply that the change in P would be 0?

External pressure is only zero in a vacuum. In a calorimeter, it doesn't matter what Pext is because it's being multiplied by delta V which is zero.
