A hot air balloon depends on the change in density as a gas undergoes a temperature change. Your brand new hot air balloon is filled with 2.140×10^3 m^3 of pure nitrogen at 26.0 ∘C and 736 torr of external pressure. After turning the burner on for a while, the temperature in the envelope rises to 120.0 ∘C, and the gas expands to 2813 m^3. Find the change in internal energy in kJ of the gas within the hot air balloon. The specific heat capacity of nitrogen is 1.040 J/g∘C.
