calorimetry

Postby Sophia Dinh 1D » Fri Mar 13, 2020 2:29 am

what is the difference between the regular and the bomb calorimeter and how do the equations change to accommodate the difference?

By regular, do you mean a constant-pressure calorimeter? This would be like an insulated styrofoam cup with an open top.

A bomb calorimeter has constant volume, so it isn't open. This is usually considered an isolated system, for no heat or matter can be exchanged with the environment.

How would we solve problems involving a bomb calorimeter when there are conditions like the volume being constant?

Regular calorimeters (the coffee cup) is done at a constant pressure, while bomb calorimeters are done at constant volume.

Regular calorimeters assume constant pressure while bomb calorimeters assume constant volume. They are both isolated systems

Regular calorimeters is done using a constant pressure, while the difference in bomb calorimeters is that they are done at constant volume.

As everyone mentioned previously, bomb calorimeters have no change in volume. You should take note that since there is no change in volume, work = 0 and that the internal energy is only affected by changes in q.

Do different calorimeters each have their own specific heat capacities?

If we were on campus would we be using calorimeters in discussion or possibly Chem14BL?

I'm pretty sure the answer to your question is yes. I remember him stating this in today's lecture but I'm not entirely sure of the reasoning/science behind it. I'm sure he'll talk more about it in the future.
