Thermo Problem

  1. Nov 4, 2006 #1
    I need a little help getting this one started...

    1.5 kg of Hydrogen gas at 8 bars and 27 degrees C are contained in a constant pressure piston-cylinder arrangement. Heat in the amount of 1740 kJ is added to the Hydrogen from a reservior at 400 degrees K. Determine: the final temperature of the Hydrogen Gas, the entropy change in the Hydrogen gas in kJ/degree K, the entropy change of the overall process (system and surroundings) in kJ/degree K, is the process reversible, irreversible, possible, or impossible?

    (I think i can get the last three parts, but i cannot seem to figure out how to get the final temperature)

    Thanks
