Homework Help: Total heat flow question

  1. Sep 26, 2016 #1
    1. The problem statement, all variables and given/known data

    n = 3.8-mol of diatomic gas is allowed to expand isothermally from Vini = 1.9-m3 to Vfin = 10.5-m3. The initial pressure is Pini = 1.38-atm. After this the gas is raised at a constant volume by a temperature ΔT = 35-K. Calculate the total heat flow into the gas.

    2. Relevant equations


    3. The attempt at a solution

    I tried to use the Q=-W formula for isothermal. But I dont know how to find the W. Other than that, I also tried to use the graph and find the integral, but in using the graph some of the information given is not used(temperature)

    Assuming that the expansion is carried out reversibly, what is your algebraic result for the amount of work that is done?
