1. The problem statement, all variables and given/known data What is the change in internal energy (in Joules) of an ideal gas that does 4.675x10^5J of work, while 2.95x10^6J of heat is transferred into the system and 7.95x10^6J of heat is transferred from the system to the environment? Calculate the change in temperature of the two moles of the gas. (R=8.314 J/mol.k) 2. Relevant equations Formulas on equation sheet relating to concept: U=3/2 nRT, change in U=Q-W 3. The attempt at a solution Me and my friend attempted two different ways, i'm probably wrong but my setup was 4.675x10^5=8.314(1)(T) 2.95x10^6=8.314(1)(T) I found the two answers and added then together and did 7.95x10^6=8.314(2)(T) found this answer, then subtracted the two answers to get a final temperature.
