Thermodynamics question(change of internal energy)

  1. Nov 7, 2012 #1
    The temperature of 2 kg of N2 changes from 300 K to 1000 K. Calculate the change of its internal
    energy during this process, assuming the ideal gas behavior, in two different methods:
    (1) Using constant heat capacity
    (2) Using the enthalpy function

    ı have to solve this question but ı can not sure about which equation should ı use..constant volume process or constant pressure process??ın other words how can ı sure about volume and pressure are constant ? Thanks

    How is the internal energy of an ideal gas related to its temperature?
