Detailed explanation-1: -False, Water does not “evaporate” at 100°C, it “boils”. Water can evaporate at any temperature, the rate of evaporation depending on the temperature and the humidity in air. Boiling is when evaporation is super fast, and ALL the water has to becomes gaseous.

Detailed explanation-2: -Water easily evaporates at its boiling point (212° F, 100° C) but evaporates much more slowly at its freezing point because of the heat energy required to evaporate the water.

Detailed explanation-3: -The condensation point of water is the same as the boiling point of water. This occurs at 212 degrees Fahrenheit or 100 degrees Celsius.

Detailed explanation-4: -Above 100 Deg C, 100 percent of liquid water will boil away or evaporate. Below 100 deg, water will evaporate based on its vapor pressure.

Detailed explanation-5: -When water is heated to a temperature of 100C, the vapour pressure equals that of sea-level air pressure. Since the air pressure can no longer overcome the vapour pressure of the water, the water boils.
