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

Re: calorimetry
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.

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

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

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

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

Re: calorimetry
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.

Re: calorimetry
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.
