A 22.5-g sample of ice at 0.0°C is added to 100.0 g of warm water at 35.0°C, and the final temperature
of the mixture is 14.0°C. (a) How much heat (in Joules) is lost by the warm water? (b) How much heat
(in Joules) is absorbed by the melted ice when its temperature increases from 0.0°C to 14.0°C?
(c) How much heat is absorbed by ice during melting at 0.0°C?
(d) What is the enthalpy of fusion of ice in kJ/mol?

(Specific heat of water =
4.184 J/(g.°C)
Explain why water boils at higher temperature under higher pressure (pure substance
saturation temperature depends on pressure). Use knowledge of energy and energy
transferring at molecular or atomic level during the phase change of a substance. You do
not need to show calculations.
• (a) the amount of heat absorbed as 1 kg of saturated liquid water boils at 100°C. (b) the
amount of heat released as 1 kg of saturated water vapor condenses. Is a >b, a=b, or a
As a substance is subjected to pressure and/or temperature changes, it may undergo condensation, deposition, freezing, melting, sublimation, or vaporization. (a) Consider the phase diagram shown below and state the cha nges that take place upon going from points A to B to C to D. (b) Is the transition from C to D exothermic or endothermic?
