Detailed explanation-1: -water from 0˚, the freezing point of water, to 100˚ C, the boiling point. However, 540 calories of energy are required to convert that 1 g of water at 100˚ C to 1 g of water vapor at 100˚ C. This is called the latent heat of vaporization .

Detailed explanation-2: -This is a process of change in the state of water that occurs if the temperature of water crosses the boiling point. The boiling point of water is the specific temperature beyond which the water tends to change its state from liquid to gas. This process occurs when the water’s temperature exceeds 100 degrees Celsius.

Detailed explanation-3: -Water can take many forms. At low temperatures (below 0oC), it is a solid. When at “normal” temperatures (between 0oC and 100oC), it is a liquid. While at temperatures above 100oC, water is a gas (steam).

Detailed explanation-4: -Water freezes at 0°C and boils and vapourizes at 100°C no matter what the conditions.

Detailed explanation-5: -Steamy Science Condensed At 100℃ it boils, thus rapidly evaporating. And at boiling point, the invisible gas of steam is created. The opposite of evaporation is condensation, which is when water vapor condenses back into tiny droplets of water. Those drops of water are called condensation.
