Which change happens when a substance melts? O The molecules of the substance move farther apart, which pulls on the intermolecular Donds between iem Heat energy overcomes the forces of attraction between the molecules of the substance, so the molecules can move more freely. O Heat energy forces the molecules of the substance farther apart until the rigid structure of the solid breaks. The vibration of the molecules produces enough heat to weaken the forces of attraction between the molecules of the substance.

The enthalpy of vaporization of water is larger than its enthalpy of fusion. Explain why.
he enthalpy (H)of vaporization of water is about seven times larger than water’s enthalpy fusion(41kJ/molvs.6kJ/mol). What does this tell us about the relative similarities among the solid, liquid, and gaseous states of water?
What is U when 1.00 mol of liquid water vaporizes at 100C? The heat of vaporization, Hvap, of water at 100C is 40.66 kJ/mol.
A 0.250-g chunk of sodium metal is cautiously dropped into a mixture of 50.0 g water and 50.0 g ice, both at 0C. The reaction is 2Na(s)+2H2O(l)2NaOH(aq)+H2(g)H=368kJ Assuming no heat loss to the surroundings, will the ice melt? Assuming the final mixture has a specific heat capacity of 4.18 J/gc, calculate the final temperature. The enthalpy of fusion for ice is 6.02 kJ/mol.
What types of forces exist between the individual particles in an ionic solid? Are these threes relatively strong or relatively weak?
A quantity of ice at 0C is added to 64.3 g of water in a glass at 55C. After the ice melted, the temperature of the water in the glass was 15C. How much ice was added? The heat of fusion of water is 6.01 kJ/mol and the specific heat is 4.18 J/(g C).
