Question

True or false

Heat is transferred to a system by either a cheap commercially available air-sourced heat pump with coefficient of performance of just 1.5, or an expensive 100% efficient electrical resistance heater. The loss of Carnot Work Potential (Exergy destruction, or T₀S_loss term) is minimum when heat is added by the cheap commercial heat pump.

Heat is transferred to a system by either a cheap commercially available air-sourced heat pump with coefficient of performance of just 1.5, or an expensive 100% efficient isothermal heat source. The loss of Carnot Work Potential (Exergy destruction, or T₀S_lossterm) is minimum when heat is added by the isothermal heat source.
