Question

8.33 kg of steam at temperature of 150 ∘C has 2.23×107 J of heat removed from it. Determine the final temperature and phase of the result once the heat has been removed if the heat is removed at constant pressure during the gas phase. For this problem, use the specific heat (at constant pressure) for water as 1850 J/kg∘C , the latent heat of vaporization as 2.256×106 J/kg , the specific heat of liquid water as 4186 J/kg∘C , the latent heat of fusion as 334,000 J/kg, and the specific heat of ice as 2100 J/kg∘C .

How much heat would need be removed to lower the temperature of the steam to the boiling point? Q1= ? J
