Bomb Calorimeter

[Rachel N 1I]

Are bomb calorimeters considered vacuums?

[Paula Sing 1J]

A bomb calorimeter is like a regular a calorimeter except a bomb calorimeter is an isolated system which is sealed and thus provides constant pressure and volume.

[Erik Khong 2E]

No, bomb calorimeters are not vacuums.

[904940852]

it is an isolated system which means that the volume is constant and matter and energy can not be exchanged

[Cynthia Bui 2H]

No, they're not considered vacuums.

[Rachel N 1I]

So for Test #1 Question 3a:

Propane is burned in the presence in the oxygen inside a sealed bomb calorimeter in contact with a heat bath and the pressure increases inside the calorimeter from 1 atmosphere to 1.5 atmospheres.

How would you justify that there is no work being done?

[Lucia H 2L]

since bomb calorimeters have rigid walls, it is impossible for volume to change, so w = -PdV and dV = 0 so w = 0.
