    • What does the coefficient of performance (CoP) for a heat pump or engine represent?
      It is the ratio of the energy transferred for heating to the input energy used in the process.
    • How does a higher CoP affect operating costs?
      Higher CoPs equate to lower operating costs.
    • What is the formula for calculating CoP?
      CoP = QW\frac{Q}{W}
    • In the CoP formula, what does Q represent?
      Q is the thermal energy supplied or removed from the system.
    • In the CoP formula, what does W represent?
      W is the work done on or by the system.
    • What is another formula for CoP in terms of temperatures?
      CoP = ThotThotTcold\frac{T_{hot}}{T_{hot} - T_{cold}}
    • What is the significance of the CoP in heat pumps?
      • Indicates efficiency of heating process
      • Higher CoP means more efficient energy use
      • Lower operating costs for consumers
