Water is being heated in a closed pan on top of a range whilebeing stirred by a paddle wheel. During the process 30kJ of heat istransferred to the water and 5kJ of heat is lost to the surroundingair. The paddle wheel works amounts to 500 N*m. The initialinternal energy of the system is 10kJ. Determine the final internalenergy (kJ) of the system.

    38 kJ

    Explanation:

    The solution is obtained using the energy balance:

    ΔE=E_in-E_out

    U_2-U_1=Q_in+W_in-Q_out

    U_2=U_1+Q_in+W_in-Q_out

    =38 kJ
