bomb calorimeter

Postby Clarissa Nava 3H » Sat Mar 16, 2019 11:54 pm

for this idea is this a closed open or isolated system?

A bomb calorimeter is a closed system since it can't absorb or release energy from/to the surroundings and it also can't gain or lose mass to the surroundings. :)

What is constant in this situation?

Volume is constant in a bomb calorimeter, and usually pressure and temperature change when combustion occurs within the bomb calorimeter. The heat released is thus taken up by the calorimeter.

So, if volume does not change, then work is equal to zero in a bomb calorimeter, right?

Work would be equal to zero, since volume is constant.

Could this be considered an isolated system because it is insulated?

so when volume is constant work is equal to 0 in any case?
