The total cost of ownership for each of these flooring types can serve as a guide for helping you to choose the right flooring solution for your organization.
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.
Examples. To get an idea of how much energy a joule actually is, it helps to look at some everyday examples. A joule is the amount of energy needed to raise the temperature of 1 gram of cool, dry air by 1.8Â°F (1.0Â°C). An average person sitting quietly produces 100 J of heat every second. The amount of energy required to lift a small apple 1 meter (3.3 feet) against the Earth's gravity is roughly equivalent to 1 J.
