Physics problem Thermodynamic cycle

  1. Oct 22, 2011 #1
    1. The problem statement, all variables and given/known data

    A mole of ideal gas with a temperature T1=300K is expanded isobarically until its volume is tripled .Then the gas gets colder isochorically untill we reach the temperature we had in the beginning 300 K.Find the work of the gas.
    Hint : We have a thermodynamic cycle .

    2. Relevant equations

    A=p* DeltaV=quantity of moles * R* deltaT

    3. The attempt at a solution
    Find A=P *3V1-V1=p*2v1=2*P*V1=2*quantity of moles*R*300....Is this correct? Show me ur solution

    Welcome to PF, Elaia06! :smile:

    Yep. That looks correct to me.

    Btw, your problem states that the quantity of moles is one.
    And do you know a value for R?
