Ah okay I see, that's what my calculations showed, that p2 < p1 (as it should for what was given). But like you said, the problem needs more clarification. The assumptions that to be made for the problem to make physical sense due to the lack of information are a little confusing. I'll for...
My apologies! Should have been looking for the replies! Its meant to be kpa I think (which might help with some confusion), not spa, the problem sheet had a few typos and I typed it as it was written and missed it. Also, I am also a little confused by 'heating' (unless they just mean energy...
Homework Statement
The question is:
One kilogram of a gas with a molecular weight of 35 is contained in a balloon. The initial conditions are 27 C and 0.025 m^3. The gas is slowly heated isothermally until the final volume is 0.05m^3. The atmospheric conditions are 100 kPa and 27 C. The p-v-T...
