That is the definition of a calorie. It is equal to 4.1868 joules.

Because light energy is needed for photolysis of water
This energy is 458,9 kJ/mol.
Carbon dioxide, water, and light energy are needed for photosynthesis.
The needed energy is 10 calories.
Tankless water heaters are low energy because they only run when the hot water is needed.
The answer is SPECIFIC HEAT!
to release the energy when needed is that we should drink a lot of water and just take a rest for at least 2 hours
You need the amount of water, the temperature of the water, and the desired temperature.
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
