WebLet's see. 4 times 200 is 800, 800 times 100; yeah, that's about right. Now, we're dealing with 100 degree water vapor, and we have to turn that 100 degree water vapor to 110 degree vapor. So we use the specific heat of vapor. 1.89 joules per gram Kelvin. Multiplied by the amount of vapor we're dealing with, 200 grams. WebHv = vaporization heat m = mass of the substance q = heat Example1 If the heat of vaporization for H20 is 2357 J/g, calculate the total amount of heat energy that required to vaporize 145 grams of H20. Solution: The heat of vaporization formula q = H v x m q= 2357 x 145 Therefore q = 341765 J
Web1 de fev. de 2024 · Water also has an exceptionally high heat of vaporization. Vaporization occurs when a liquid changes to a gas, which makes it an endothermic reaction. Water's heat of vaporization is 41 kJ/mol.
