Could Somebody who knows help me out with this question, would really apricate it. I'm really struggling with these to questions and would really love a point in the right direction. If you could at least just show me what equation I might need that'd be a life saver.

An ideal gas, with specific heat at constant volume of 1.005 kJ kg-1,
is heated at constant pressure from an initial temperature of 300 C to
a final temperature of 1100 C. Determine the heat energy added to
the gas in this process, per unit mass.


Dry saturated steam enters a condenser at a pressure of 1 bar, and
leaves as saturated water at the same temperature. No work is done
during the condensation process, and changes in gravitational
potential energy and velocity can be considered negligible.
Determine the heat removed from the steam during the condensation
process, per unit mass.

This question is very similar to the specific heat capacity of a solid problem. In calculating the thermal energy Q need to supply to heat up a solid of mass m from initial temperature T1 to T2 with the specific heat capacity of c is
Q = m c (T2T1).
