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.
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
The amount of energy required to freeze 2.5 grams of water is approximately 4.2 kJ. This energy is used to remove the heat from the water, allowing it to change from a liquid to a solid state at 0 degrees Celsius.
The energy released when water freezes is about 334 J/g. Therefore, for 65.8g of water, the energy released during freezing would be approximately 22,000 J.

You need to know the initial temperature.

Approximately 6.1% of the world's energy is generated using wind turbines.
None. When water freezes it _releases_ energy (the heat of fusion, 333.55 kj.kg). To keep it from freezing, simply keep the energy constant. If the ambient temperature is below zero C (32 F) the rate of energy loss will depend on the temperature of the air and the thermal resistance (insulation value) of the water's container, and other factors such as wind speed. In those conditions you must replace the energy lost to prevent the water from freezing. However, the energy needed depends on the rate of loss, not on the amount of water.
The amount of energy required to freeze 2.5 grams of water is approximately 4.2 kJ. This energy is used to remove the heat from the water, allowing it to change from a liquid to a solid state at 0 degrees Celsius.
No heat (energy) is required to freeze water (from liquid to solid). Freezing RELEASES energy (heat), as it is an exothermic event. If you want to know how much energy is release, you need to know the heat of fusion for water, and then multiply that by the mass of water being frozen.
Air compressor alone consumes about 50 to 60 % of energy generated by a gas turbine..
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
Around 10% of the world's energy is generated from nuclear power.
The energy released when water freezes is about 334 J/g. Therefore, for 65.8g of water, the energy released during freezing would be approximately 22,000 J.
