- Match each of the terms given below with the particular constraints that it implies about a thermodynamic process. isothermal isobaric A. dq = 0 Β. ΔΡ = 0 C. dw = 0 D. AV = 0 isochoric ◆adiabatic E. An = 0 F. AT=0A monatomic ideal gas is initially in state A. The gas undergoes a transition from state A by the three different processes shown, where process III is isothermal. In which process is energy added to the gas by heating? Explain briefly.em 5 A NATO base in northern Norway is warmed with a heat pump that uses 7.0°C ocean water as the cold reservoir, Heat extracted from the ocean water warms fluid to 80° C; this warmed fluid is used to heat the building When the system is working at full capacity, 2000 kW of heat are delivered to the building at the cost of 600 kW of electric energy.
