Specific heat(Cice) = 2.108 J/g-°C, Latent heat of fusion of ice (L) = 334 J/g, Specific heat(Cwater) = 4.184 J/g-°C, Latent heat of Vaporization(V) = 2260 J/g, Specific heat(Csteam) = 1.996 J/g-°C
Heat energy required to heat ice from -40°C to 0°C (Q1):
Q1 = mCice∆T = (60 g)*(2.108 J/g-°C)*(0°C - (-40°C)) = 5059.2 J
Heat energy required to melt ice (Q2):
Q2 = mL = (60 g)*(334 J/g) = 20160 J
Heat energy required to heat water from 0°C to 100°C(Q3):
Q3 = mCwater∆T = (60 g)*(4.184 J/g-°C)*(100°C - 0°C) = 25104 J
Heat energy required to Vaporize water(Q4):
Q4 = mV = (60 g)*(2260 J/g) = 135600 J
Heat energy required to heat steam from 100°C to 140°C(Q5):
Q5 = mCSteam∆T = (60 g)*(1.996 J/g-°C)*(140°C - 100°C) = 4790.4 J
Total heat required = Q1 + Q2 + Q3 + Q4 + Q5 = 19713.6 J = 0.19 MJ
