How much heat is required to warm 225g of ice from -48.6C melt the ice warm the water from 0.0C to 100.0C boil the water and heat the steam to 173.0C

  • Chemistry - ,

    q1 = heat to move ice from -48.6 to O.
    q1 = mass ice x specific heat ice x delta T.

    q2 = heat t melt ice at zero to liquid water at zero.
    q2 = mass ice x delta H fusion.

    q3 = heat to move liquid water from zero C to 100 c.
    q3 = mass water x specific heat water x delta T.

    q4 = heat to vaporize water at 100 to steam at 100.
    q4 = mass water x delta H vaporization.

    q5 = heat to move steam from 100 C to 173.0 C.
    q5 = mass steam x specific heat steam x delta T.

    Total Q = q1 + q2 + q3 + q4 + q5.
