A) How much heat needes to be taken from 0.5 kg of ethyl alcohol as a gas at its boiling point of 78 C to a solid at its freezing point -114 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?
B) If a piece of irion (c=450 J/ kg C) at 65 C is dropped into 0.250 kg of ethyl acohol at 25 C and the final temperature of the two comes to 35 C what was the mass of the piece of iron?
C) if 0.35 kg of solid ethyl alcohol at -114.0 C is put in a large wll insulated jug holding 2.5 kg of liquid ethyl alcohol initially at 35 C what will the final temperature be after all the solid form has melted and come to equilibrium?
