It's just a ranking task that says Rank from greatest to least the temperatures of the ideal gases below that contain various amounts of internal energy and vorious number of molecules in various volumes." Each case has different internal energy, number of molecules, and volume.

How can I find the temperature of something if I'm give the internal energy(U), volume(V), and number of moles(N). I thought it'd just be pv = nrt but I am not sure what to do with the internal energy or how to use it with pressure. Thanks.

...anyone?

Im having trouble figuring out how to solve this ranking task, I've tried nearly everything and I'm not getting the right answers. http://wps.prenhall.com/wps/media/objects/223/229290/rt/pdf/work068.pdf .. the answer are F, A, C, E, B, D where A and C are equal.

Find the hydrostatic force on one side wall of the pool when it is full of water. how do i go about solving this? image is attached

I understand now, thanks for clearing that up for me.

if i have to find the average speed between two points, do i just subtract distance2 from distance1 and divide by the time interval? so it could be possible for the average speed to be 0 if whatever traveled equally length in both negative and positive direction?

Question: A spherical bubble of radius 1 is surmounted by a smaller, hemispherical bubble, which in turn is surmounted by a still smaller hemispherical bubble, and so forth, until n chambers including the initial sphere are formed. What is the maximum height of any bubble tower with n chambers...
