WebThe pure gaseous forms are easier to compare boiling points, but the acid forms are more commonly dealt with in chemistry. I'll just assume you meant the pure forms of both; hydrogen chloride and hydrogen fluoride. Hydrogen chloride has a boiling point of 188.10 K and hydrogen fluoride has a boiling point of 292.6 K. Webmelting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change. When all the solid has melted, additional heat will raise the temperature of the …
