Heating Cooling Systems

I know the equation of the inclined portion of the cooling curve for water heating is Q = mxsx you delta T, but what is the equation of the flat. From what I can tell … Melting portion to the equation Q = MHF, where Hf is the heat of fusion of the substance in J / g. For part boiling (vaporization portion) of the curve heating / cooling of the equation is Q = MHV. Each of these two parts are independent of the temperature T is not a variable in the equations. Hope this is helpful to you. JIL HIR
