I have done a series of thermodynamics questions covering heat transfer, internal energy, temperature pressure etc. I have a new one but I am unsure how to start it, its unlclear whether i know certain things. I can do the question form looking back at pervious questions, if i knew how to start.
0.36m cubed of air at a pressure of 1.1MN/m2 and 339k is given an energy of 3.4MJ by means of heating at a constant pressure. The air is then allowed to expand to a volume of 1.44m3 according to the law pv power of 12= a constant.
For each process calculate the final temperature, the work tarnsfer and the change in internal energy.
I am assuming the question is two parts, and therefore i don't know
temperature two/final temp or volume 2. that's why I am unsure how to get the final volume
how would i find the final temperature in order to carry out the rest of the question?
any help whould be great!
