Webheat of vaporization: The energy required to transform a given quantity of a substance from a liquid into a gas at a given pressure (often atmospheric pressure). Water's Heat of Vaporization Water in its liquid form has an unusually high boiling point temperature, a value close to 100°C. WebStep 2: Plug in these values into the heat equation. Q = m x C x Δt. Q = 53 g x 4.184 J/g°C x 33°C. Q = 7300 J. How much heat is released when 21 g of Al cools from 31.0°C to 27.0°C? Step 1: Identify what is given in the problem. m = 21 g. If the substance is known, the value of C can be found on a chart like the one above. C = 0.89 J/g°C.
