Answer #1

Q = m Cp dT

Q = 19.5 x 4.184 x (100-27)

Q1 = 5956 J

Q2 = heat of vaporization x mass

        = 2260 x 19.5

        = 44070 J

total heat = Q = Q1 + Q2

        Q = 50026 J

heat lost by water = heat gain by skillet

50026 = 1450 x 0.444 x dT

dT   = 77.7 oC

change in temperature of the skillet = 77.7 oC
