This depends how many kilowatts are running through the element, but it can take anything from one to two hours.
A heating element inside of the water pipes heat the water as it passes through. Each time the faucet is turned on, the element is turned on. When the water goes off, so does the element. Thus, water is heated only when needed rather than being held in a storage tank.
The specific heat of water determines how much energy is needed to heat water.
depends on the amount of water
Specific Heat of Water = 4.1813 kJ/l/K If starting temperature is say 10°C - 500 Litres * 4.1813 (100°C - 10°C) = 188158.5 kJ 188158.5kJ / 3kW = 62719.5 Seconds = 17.42 Hours
If there is water in it you can heat it.
You can not get heat from cold water, The engine has to run long enough to get the water in the engine HOT. That is were you get heat from HOT WATER-- Coolent
Yes. As long as there is sufficient heat water can evaporate in the dark.
Water will be available on the Earth as long it survives against the Sun's heat. Prof. P.M.NATARAJAN
It depends on the volume of water present, and the heat of the water to start with.
the water will not sterilize if you boil the water! the water still has bacteria in the water even if you heat it up; that's because some bacteria is heat resistant and will not die through the process.
If you burn a peanut it will keep aflame for a long time underwater, and boil the water
water has a high specific heat, meaning it stores a lot of heat energy.
