Calorimeters

[McKenna_4A]

is a bomb calorimeter constant V or P??

[Ryan 1K]

A bomb calorimeter maintains a constant V. Since V is constant, any increase in gas molecules would result in an increase in pressure since there would be more particles in the same V.

[Betania Hernandez 2E]

A bomb calorimeter is constant volume which means that since there is no change in volume then there is no work done.

[chrisleung-2J]

A bomb calorimeter only maintains constant volume, causing no work to result from pressure or volume changes and thereby resulting in all measured heat directly correlating with the change in internal energy.

[Hailey Kim 4G]

A bomb calorimeter measures specific heat at a constant volume.

[Jasmine Fendi 1D]

A bomb calorimeter stays at constant volume! Because of this, there is no work being done to the system.

[Brian J Cheng 1I]

Constant volume as many have said. It's not really constant pressure because the reaction inside can keep changing the pressure.

calorimeters maintain the same volume so constant volume

[Asha Agarwal 1E]

It is a constant volume calorimeter.

Is there a difference between a regular calorimeter and a bomb calorimeter?

[Ryan 1K]

Is there a difference between a regular calorimeter and a bomb calorimeter?

Yes, if you're talking about the simple calorimeters that are used in high school labs, which basically consist of thermometers suspended in a container filled with water. The difference between these calorimeters and bomb calorimeters is that simple calorimeters maintain a constant pressure (since it's not completely enclosed, and gases can enter and exit the container), while bomb calorimeters maintain a constant volume (sealed so gases cannot flow between the system and the surroundings).

Ah, I see. That makes a lot more sense now. So for this class and for the midterm, which one will we be dealing with more?

[CMaduno_1L]

To answer the question above, I believe it's safe to expect to see both variations. We should know the different conditions that correspond to each type of calorimeter because both types show up in the homework problems. Hope this helps!

I think since the midterm only has a limited number of questions, we will see at most one of each. I don't expect there to be more than one question dealing with the different conditions between the two calorimeters.

calorimeters keep a constant volume

[EvanWang]

A bomb calorimeter has rigid walls that do not allow for expansion, therefore it is constant volume. A system with constant pressure would be open to the environment.

[KHowe_1D]

A bomb Calorimeter has a constant volume.
