How much heat is required to heat 28 g of
solid silver from 130

C to liquid silver at
961

C? The specific heat of solid silver is
0.235 J/g ·

C, and the heat of fusion of silver at its melting point of 961

C is 11.3 kJ/g.
Answer in units of kJ

  • chemistry -

    q1 = heat to raise T from 130 to 961.
    q1 = mass Ag x specific heat solid Ag x (Tfinal-Tinitial) [Note: Tfinal is 961).

    q2 = heat to melt Ag at 961C.
    q2 = mass Ag x heat fusion.

    Total q = q1 + q2
