A refrigerator has a coefficient of performance of 4.0. When removing 2.4x10^4 J from inside the refrigerator, how much energy is sent into the environment?

  • Physics - ,

    Coefficient of performance = energy removed from fridge / ( total energy expelled – energy removed from fridge )
    k=Q1/(Q-Q1)
    Q=Q1(k+1)/k=2.4•10⁴•5/4=3•10⁴ J
