Water is a transparent and colorless substance which is a constituent of earth’s stream, lakes, rivers etc. Its chemical formula is H2O, which means that one of its molecules contain a covalent bond of one oxygen with two hydrogen atoms.
Boiling point of a substance is a temperature where vapors pressure equals to the pressure surrounding the liquid. The boiling point of water is 100℃. At this pressure, water will never be solid.
Freezing point of a substance is a temperature where liquid changes into a solid state. The freezing point of water is 32℉ or 0℃. At this pressure, water will never be liquid.
Now the question arises that can freezing and the boiling point of water be same?
Yes, the boiling and freezing point of water can be same. Water releases energy when it changes from liquid to solid. The Same energy is required to change back from solid to liquid. During the change of state that is solid to liquid or liquid to solid, there is no change in temperature only release and uptake of energy took place. This process is the heat of fusion. Let consider an ice cube in your freezer. When we take out an ice cube from the freezer and put it in the warm kitchen, the heat from the surroundings starts entering to the ice cube. And at the melting point, there is enough thermal energy to break down these intermolecular forces. What we observe that there is no change in temperature but the bonds are breaking and the solid starts to melt.
A similar explanation can be used for a reverse process that is freezing of water.
