An intrepid explorer takes 400 g of ice from the cold Siberian environment, where the temperature is –40 degrees and places it in a kettle inside his mobile laboratory. The ice melts and he heats the water to +40 degrees. What is the total amount of heat absorbed by the explorer’s sample of H2O?

  • Thermodynamics - ,

    q1 = heat absorbed to raise T from -40 to zero.
    q1 = mass ice x specific heat ice x (Tfinal-Tinitial)

    q2 = heat absorbed to melt ice at zero to form liquid water at zero..
    q2 = mass ice x heat fusion.

    q3 = heat absorbed to raise T liquid water from zero to +40C.
    q3 = mass water x specific heat water x (Tfinal-Tinitial).

    Total q = q1 + q2 + q3.
