WebIf temperature increases, as it does in most reactions, a chemical change is likely to be occurring. This is different from the physical temperature change. During a physical temperature change, one substance, such as water is being heated. However, in this case, one compound is mixed in with another, and these reactants produce a product. WebThe effects of dissolved substances in boiling point and melting point are :-. 1. On the boiling point of water. Some of the solute (salt) molecules occupy the surface, reducing the effective area for evaporation. Since evaporation is suppressed, the boiling point is raised. Salt water consequently boils at a temperature above 100 0 C.
