How much does it cost to boil a full kettle of water?
The cost to boil a full kettle of water depends on the energy efficiency of the kettle and the cost of electricity in your area. On average, it could cost around 2 to 10 cents to boil a full kettle of water.
How much energy is required to evaporate 21.6 tons of water?
The needed energy at 100 oC is 48751 MJ.
If 30.86g of H2O is frozen (from liquid to solid) how much heat energy is required?
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.
Can I drink boiled water?
It is possible to have boiling ice water. If the pressure is increased enough, the melting temperature will also increase (the bonds would need more energy to break). Some molecules will have the required energy to vaporize near the surface while much of the water is still ice.
How much energy is required to melt 56g?
The energy required to melt a substance can be calculated using the formula: Energy = mass x heat of fusion. For water, the heat of fusion is 334 J/g. Therefore, the energy required to melt 56g of water would be 56g x 334 J/g = 18,704 J.
How Much energy does it take to boil 100 ml?
The energy required to boil 100 ml of water at room temperature (20°C) to boiling point (100°C) is about 4200 joules. This is the amount of energy needed to raise the temperature of water by 1°C per gram.
How much energy is required to hard boil an egg?
Absolutely none:) ;) :) GET SOMEONE ELSE TO DO IT FOR YOU HA HA HA!!!

Why you should only put as much water as you need into the kettle to boil and not just fill you up?
As mass in a sample increases, it requires more energy to alter the temperature. The energy required is equal to the specific heat of the sample, multiplied by the mass, multiplied by the temperature change.
Why do you put lids on pans?
The use of a lid when cooking reduces the amount of heat escaping from the cooking area. Reducing the amount of time required for cooking and thereby reducing the amount of energy needed. This in turn reduces the amount of energy-required to pay the electricity bill. A good way to prove this point is to boil a pot of water with a lid and one without a lid and time how long they take to boil. Then see how much difference there is in the setting needed to make each simmer.
Is the amount of heat required to boil 1kg of water equal to the amount of heat required to melt 1kg of ice?
No, the amount of heat required to boil 1kg of water is much higher than the amount of heat required to melt 1kg of ice. Boiling water requires additional heat to overcome the latent heat of vaporization, while melting ice only requires heat to overcome the latent heat of fusion.

Can the energy in a peanut heat water?
Yes it can by the chemicals being released to boil water.
What are 4 ways you can save energy at home?
switch off lights when your not using them only boil as much water that you need don't use too much water in the shower switch off the PC when not in use
What is Water absorption coefficient formula?
The formula for water absorption coefficient is based on Lambert-Beer's Law and is expressed as: α = 2.303 / L * log(I0/I), where α is the absorption coefficient, L is the thickness of the material, I0 is the incident light intensity, and I is the transmitted light intensity.
