the specific heat capacity of water is 4200 J / kg °C
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
Water absorb heat from sun. it releases heat into the air.
Microwaves heat water by causing the water molecules to vibrate rapidly, generating heat through friction.

Yes! Water is a heat sink.
A heat pump water heater uses electricity to move heat from the air or ground to heat water in a household. It is more efficient than traditional water heaters because it does not directly generate heat, but rather transfers existing heat to the water. This process can save energy and reduce costs for heating water in a home.
When water evaporates, heat from the surroundings is absorbed to break the bonds between water molecules, turning liquid water into water vapor. This heat energy is stored in the water vapor as latent heat, increasing its kinetic energy.
Hot water merges with the cold water, and any heat is dissipated.
Salt water holds more heat than fresh water
The heat you feel from boiling water is primarily convective heat, which is heat carried by the physical movement of the water molecules. In addition, there may also be some radiant heat from the steam rising off the boiling water.
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
Because heat changes the temperature of the water
