PV diagram Quasi-static cycle

    1. The problem statement, all variables and given/known data
    Hi guys can someone tell me if I am wrong, or missing reading this question.

    For part a I need to draw a PV diagram now it states that is is being expand isothermally yet when I look at the pressure it dose not change, which is confusing me beacuse it dose in a isothermal expasion other there will be no work done on the system, in the next part it say the gas is heated to a temp and the pressure increase to 2.00atm which mean it has not change at all, so it this a typo in the question or have I missed read it completly
    2. Relevant equations


    3. The attempt at a solution

    Who says the pressure doesn't change during the isothermal expansion of an ideal gas? What does the ideal gas law tell you?

    Sorry I am not implying the pressure dose not change I think it dose, but the question is telling me it starts with an intial pressure of 2.00at and then increases to 2.00atm this is my confusion.

    I don't see how you can possibly interpret the problem statement that way. How did you arrive at the result that pressure stays at 2 atm?
