Suppose that 32.7 J of heat is added to an ideal gas. The gas expands at a constant pressure of 1.45 104 Pa while changing its volume from 3.12 10-4 to 7.55 10-4 m3. The gas is not monatomic, so the relation does not apply.
(a) Determine the change in the internal energy of the gas.

Answer ________J

(b) Calculate its molar specific heat capacity CP.

Answer ________J/(mol · K)
