The process that requires water to gain 2260 joules of energy per gram is known as specific heat capacity. Water has a specific heat capacity of 4.18 J/g°C, which means it takes 4.18 joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.
The process of vaporization, where water changes from liquid to gas, requires 2260 Joules of energy per gram to occur.
The process you are referring to is called water having a specific heat capacity of 4.184 J/g°C. This means that it takes 4.184 joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius. In this case, to gain 2260 joules of energy, it would take approximately 540.3 grams of water.
Energy is absorbed when water is vaporized. This is because the process of vaporization requires breaking the hydrogen bonds between water molecules, which requires energy input to overcome the intermolecular forces holding the liquid water together.
An example of an endothermic process is evaporating. Evaporation requires an input of energy to convert liquid water into water vapor, so it is an endothermic process.
Photosynthesis is not a spontaneous process because it requires energy input from sunlight to convert carbon dioxide and water into glucose and oxygen.
The process of vaporization, where water changes from liquid to gas, requires 2260 Joules of energy per gram to occur.
Water gains the most heat energy during the process of vaporization, when it changes from liquid to gas. This requires a large amount of energy to overcome the intermolecular forces holding the water molecules together.
When 2 grams of water is converted from liquid to gas at its boiling point, it requires an input of approximately 2260 joules of energy. Conversely, when 2 grams of steam condenses into liquid water, it releases around 2260 joules of energy.

To convert ice to water on the moon, energy is needed to break the hydrogen bonds holding the water molecules together in the solid ice lattice. This process requires the input of heat energy to overcome the enthalpy of fusion of water, which is approximately 334 joules per gram.
Evaporation.
Photosynthesis requires energy input in the form of sunlight to convert carbon dioxide and water into glucose and oxygen.
The total energy in the kettle system will be 2000J. However, the energy will be distributed different ways. Some will go into heating the water, some will go into changing the water into steam (which takes a LOT of energy), and some will be lost as radiant heat energy. The specifics depend on the kettle itself, and how much water you have in the kettle.Changing one milliliter of water by one degree requires 4.186 J of energy, but to convert it into steam requires 2259.36 J per ml
Vaporization
The energy released when condensing water vapor is known as the heat of condensation. It takes 2260 Joules of energy to condense 1 gram of water vapor. So, for 6.0 grams of water vapor, the energy released would be 6.0 grams * 2260 Joules/gram = 13,560 Joules.
Energy is absorbed when water is vaporized. This is because the process of vaporization requires breaking the hydrogen bonds between water molecules, which requires energy input to overcome the intermolecular forces holding the liquid water together.
334 Joules per gram ... at 0oC, 334 Joules of energy must be added to melt one gram of ice from solid to liquid form, and 334 Joules of energy must be removed to freeze one gram of liquid water to form ice.
