1.The problem statement:
Hydrogen (H2) is at standard conditions in a closed tank, V = 5l, and then it's cooled down for 55K. Find delta U and Q.
2. Questions:
If it says standard conditions, can I just use pV = nRT to find n and then deltaU = j/2*nR(delta)T? Also, is there any work that a gas does, if the V is constant?
I'm a bit confused about certain terms here, so I'd like someone to explain it to me, as I'm preparing for an exam at university.Now, I've done some work and my result for U was 254.9J, but I don't know if I'm correct here.
