7. Substance A evaporates at temperature T. Calculate the specific heat of evaporation at the same temperature. Write an equation for the dependence of the heat of evaporation of substance A on temperature. Take the heat capacities of saturated steam and liquid from the reference book, assuming that they are constant in this temperature range. The heats of evaporation at normal boiling point are given in the table.
