Explanation:
Detailed explanation-1: -It requires energy to change from a liquid to a gas (see enthalpy of vaporization). In addition, gas molecules leaving the liquid remove thermal energy from the liquid. Therefore the temperature of the liquid remains constant during boiling.
Detailed explanation-2: -Answer and Explanation: The water at the bottom of a geyser won’t boil because of the pressure the water experiments at the bottom of the geyser. High pressures will be able to maintain water at high temperatures without the water evaporating or boiling away.
Detailed explanation-3: -Boiling the water kills microorganisms such as bacteria, viruses, or protozoans that can cause disease. Boiling makes the tap water microbiologically safe.
