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.
How much heat (in joules) is required to raise the temperature of 30.0 kg of water from 18Â°C to 81Â°C?est Answer: Q(heat energy) = m*c* delta T where c is the specific heat capacity of ur material, in this case, water. c(water) = 4.18J/ g* K So Q = 30000g * 4.18 J/g*K *63K = 7900200J = 7900.2kJ.
