how much heat is needed to change 20 g of solid water at 0 c to liquid water at 15 c?

  • chemistry -

    q1 = heat needed to melt solid water at zero to liquid water at zero.
    q1 = mass x heat fusion.

    q2 = heat needed to raise T from zero C to 15 C.
    q2 = mass water x specific heat water x (Tfinal-Tintial)
    Total Q = q1 + q2
