Bomb Calorimeter

Postby Lauren To 1E » Tue Feb 09, 2021 10:41 am

Are bomb calorimeters always isolated systems?

Hi!

Considering bomb calorimeters are well-insulated (no heat is going in or out) and cannot be opened (to move matter in or out) during the calorimetry experiment, I would think that bomb calorimeters are always isolated systems.

I'm not entirely sure if there are any exceptions. Someone please let me know!

I hope this helps :-)

Hello! If you see bomb calorimeters in a question, it's probably safe to assume that they are referring to an isolated system. This is because bomb calorimeters are sealed, so there's no exchange of mass with the system's surroundings. And since it is insulated, there would also be no energy exchange with its surroundings.

Hope this helps!

Yes, bomb calorimeters are always isolated systems, as they are fully sealed and insulated.

wait what exactly are bomb calorimeters? has this mentioned in lecture before? if so, when/where and how solid should we be on this topic?

I believe it was mentioned in lecture 12 but it may have been lecture 11. I know its in one of the two.

Yup, bomb calorimeters are isolated systems. For closed system problems, coffee cup calorimeters are the usual example, and for isolated systems, bomb calorimeters are the usual example.

Yes, they are! We are assuming bomb calorimeters are completely insulated (so no energy/heat can be exchanged with the surroundings), and they are a fixed volume (so no matter can be exchanged with the surroundings). Therefore, they are isolated systems.

They are closed, insulated environments. I would say theyre always isolated.

Yes! In the context of this class, I would assume that all bomb calorimeters are isolated systems.

Bomb calorimeters are isolated systems, which do not exchange heat/matter with the surroundings.

Hi! Yes you're correct, bomb calorimeters are isolated and sealed systems.

Yes, bomb calorimeters will always be sealed and isolated.

Bomb calorimeters are sealed and insulated, so it can be assumed that they're all isolated systems.
