Melt.
Because of the heat of fusion the ice is now water
The enthalpy of dissolution of NaCl in water is the amount of heat energy released or absorbed when NaCl dissolves in water.
The phase change where the greatest amount of energy is absorbed by 1 gram of water is during the transition from liquid to gas, known as vaporization or boiling. This process requires a significant amount of heat energy to break the intermolecular bonds and change the water molecules from a liquid state to a gaseous state.
The amount of energy generated from freezing 2.5g of water can be calculated using the specific heat capacity of water and the heat of fusion for water. The energy released would be equal to the heat of fusion of water (334 J/g) multiplied by the mass of water (2.5g). By multiplying these values, you can determine the total energy released during the freezing process.
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.
Melt.
The energy absorbed by one gram of ice as it melts is known as the heat of fusion for water. This energy is required to break the intermolecular forces holding the ice molecules together and convert the solid ice into liquid water at its melting point.
The heat energy released or absorbed during a change of state of water is called latent heat. This energy is used to break or form intermolecular bonds without changing the temperature of the substance.
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.
The amount of energy needed to change a given mass of ice to water at constant temperature is called the heat of fusion. This is the heat energy required to change a solid to a liquid at its melting point.
Water molecules have the highest amount of energy when they are in the gaseous state, such as steam or water vapor. In this state, the molecules have absorbed enough energy to overcome intermolecular forces and move more freely.
Energy is absorbed when water changes state from a solid to a liquid to a gas. This energy is used to break the bonds between water molecules during melting and vaporization. It is known as the latent heat of fusion and latent heat of vaporization, respectively.
The water molecules release energy in the form of infrared photons that are absorbed by the surrounding air.

In nuclear fusion of hydrogen, the transformation of mass into energy occurs. This is in accordance with Einstein's equation E=mc^2, where a small amount of mass is converted into a large amount of energy.
The size of a sponge does affect the amount of water absorbed. The bigger the sponge the more water absorbed.
