Expert Solution
Step 1

Given :- 

Mass of Ice (solid H2O) =  976. g

Temperature of Ice (solid H2O) = -10.0 °C. 

Temperature of Steam (gaseous H2O) = 126.0 °C 

We know that, 

Specific heat of Ice = CIce = 2.03 J/g.°C 

Specific heat of Water = CWater = 4.184 J/g.°C 

Specific heat of Steam = CSteam = 1.99 J/g.°C 

Heat of fusion of Ice = ∆Hf(Ice) =  334 J/g 

Heat of vaporization Water = ∆Hv(Water) = 2260 J/g
