a. How much heat needs to be taken from 0.5 kg of ethyl alcohol as a gas at its boiling point of 78.00 C to a solid at its freezing point -1140 C if the latent heat of vaporization is 850,000 J/kg and its latent heat of fusion is 104,000 J/kg, and the specific heat is 2400 J/(kg C).

b. If an piece of Iron (c = 450 J/kg C) at 65.00 C is dropped into .250 kg of ethyl alcohol at 25.00 C and the final temperature of the two comes to 35.00 C what was the mass of the piece of iron?

c. If .35 kg of solid ethyl alcohol at -114.00 C is put in a large well insulated jug holding 2.5 kg of liquid ethyl alcohol initially at 35.00 C what will the final temperature be after all the solid form has melted and come to equilibrium?
