thanks, i will give that a try and then reply again when i come up with something. i think the 5 seconds is just enough for relaxation time so that we don't have to worry about anything during the relaxation time.

I went with 6.6*10-27 instead of 10-29 because the latter made way to much of a temperature increase. Other than that, I think I can move on from this point. I ended up getting that the change in heat coming in or leaving the system was zero. Does that make sense? I mean, it is adiabatic, so...

Homework Statement A well insulated 2 liter thermos bottle contains 500 ml of boiling liquid Nitrogen, and the remainder of the thermos has Nitrogen gas at 1 atmosphere in equilibrium with the liquid. You drop a 200 gram piece of iron at 25 degrees Celsius inside and seal the cap. After 5...

start with a free body diagram and the answer will appear

I thought of a comment... under the fifth-root-radical it is suppose to be (# of Pascals in an atmosphere)/(20 atmospheres)(# of Pascals in an atmosphere) all cubed... because it is Pinitial / Pfinal. I did it with the Pascals because that helps me to work with my units. I think it should be...

Oh holy crap, it is a disaster... well, the important parts can be made out. it would be nice to have a little chalk board we could draw on. Maybe I'll continue the problem after a while.. that is enough for now. Hopefully I will get better and faster at inputting this stuff.

Homework Statement 14 grams of Nitrogen at 20 degrees Celsius in 1 atmosphere of pressure is compressed to a pressure of 20 atmospheres. What is its final temperature and what is the work done on the gas if the process is adiabatic? Obtain the compression ratio (i.e. Vmax/Vmin). How much...

yes... that is so awesome! I had been working on the problem just before I came here, and I had noticed that I was overcomplicating it. I did figure out that the work done would be the area enclosed, and I was able to show that graphically for the sloped line. Your formulas helped me to prove...

hi all, I'm new.. signed up for e-mail today like the site very much

Homework Statement A gas is compressed, allowed to expand linearly, and then cooled at constant volume as shown in the P-V graph. How much work is done by the gas in this cycle? in the graph: compression is a straight line at P(atm)=3 that goes from V(liters)=1 to V=5; cooling occurs at...
