Chet, that is true. Bystander, I see what you are getting at now! In both cases, (Pv)/RT = 1 so (P1v)/(RT1) = P2v/RT2 and R and v will cancel out of each side showing that the following relationship is independent of them: P1/T1 = P2/T2 and now I can solve. Thats what I get for still...

Why solve for v, or why am I justified in saying that? v = (RT1)/P1 and everything on right hand side is known (if I know what R to use). Why am solving for v in the first place-- I can use the fact that v is constant through the process (remember, the system is a constant volume closed...

I was assigned a problem in my Engineering Thermodynamics class as follows: Problem: An ideal gas in a rigid closed container undergoes isochoric heating from T1 = 27 C to T2 = 77 C. Initial gage pressure is 300 kPa, pressure of surroundings is 1 atm. Find the final gage pressure. The way to...

Hello all, My name is Preston. I am Mechanical and Manufacturing Engineering (double) Major, and I'm in my sophomore year. I personally find physics fascinating. However, if I had to pick a particular area of physics since it basically entails (or seeks to entail) the way the entire universe...
