This is a saving of $82 per square foot, each and every year. Multiplied out over a 100,000 ft 2 space, choosing carpet over VCT could save you $8200 per year. 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.
It's used to turn the water into steam (the technical term for that energy is the latent heat of vaporization), and the steam stores that energy. It's a lot of energy: 1 gram of steam has enough energy to raise 7 grams of water from room temperature to boiling. When steam condenses back into water on the cooler surface of food, it gives that energy back, quickly heating the food surface. This is why steam can burn your skin badly and quickly. On the other hand, steam isn't very dense--in fact, it's over 1,600 times less dense than water--and, as soon as the surface of the food reaches the same temperature as the steam, you no longer get the huge benefit from condensation.
