A Carnot engine operates between 170°C and 23°C. How much ice can the engine melt from its exhaust after it has done 4.5 104 J of work? (kg)

  • Physics -

    T1=273+170=443 K
    T2=273+23=296 K
    efficiency =(Q1-Q2)/Q1 =W/Q1
    efficiency =(T1-T2)/T1
    W/Q1 = (T1-T2)/T1
    Q1=W•T1/(T1-T2)
    Q1= r•m
    r= 333•10⁵ J/kg
    W•T1/(T1-T2) =r•m
    r= W•T1/(T1-T2)•m=...

  • Physics -

    m = W•T1/(T1-T2)• r =...
