334 Joules per gram ... at 0oC, 334 Joules of energy must be added to melt one gram of ice from solid to liquid form, and 334 Joules of energy must be removed to freeze one gram of liquid water to form ice.

They are examples of states of matter.
Due to it's polarity. Water consists of 2 hydrogen molecules and 1 oxygen, hence, H20. The hydrogen molecules have a slight positive charge and the oxygen has a slight negative charge. Water can form bonds with other polar molecules, as well as interact with positively or negatively charged ions.

The heat of vaporization is about 2258 joules/gram46 x 2258 = 103,868 J ~ 103.9 kJ(Using the rounded value 2260 joules per gram, about 104 kJ)it is already at boiling point so in theory zero energy is required.I think the question is asking what energy is required to free the water from its liquid state to the vapour state.At 101325Pa, (1 atmosphere in old money), the latent heat of evaporation of water is 2256.7 J/g.So 2256.7 * 46 = 103808 Joules
A cooling curve for pure metals shows the changes in temperature as a molten metal solidifies. It typically consists of a gradual decrease in temperature until the metal solidifies, followed by a period where the temperature remains constant as the latent heat of fusion is released, before the temperature decreases further. The cooling curve can provide important information about the solidification process and the resulting microstructure of the solid metal.
"Water" = the common name for 100% h20.
