Once the water is at 100 Â°C, still more energy must be added. This is given by the heat of vaporization, which for water is 2261 kJoules per kilogram. So, in the example, once the 1 kg of water. is at 100 Â°C, this amount of energy must be added to boil it: 1 kg * 2261 KJoules/kilogram = 2261 kJoules.
So anybody who does talk about energy, rarely speaks in Joules. We instead multiply power back by time again and have the unit, the kilowatt-hour. A kilowatt, a thousand Joules/second, times 3600 seconds in an hour, is 3,600,000 Joules - 3.6 megaJoules (MJ).e all know the Watt is a unit of power consumption and have an idea how quickly a 1500 Watt kettle boils water. The unit of energy is the Joule - a Watt is just a flow of one Joule per second. The other popular unit of power is the horsepower.
