WebWhat is the boiling point in chemistry? The boiling point is the temperature at which a liquid begins to convert to gas. As we discussed in the intro, boiling is when the liquid turns into a gas by forming bubbles that travel to the surface. Before we get ahead of ourselves, let's first talk about the processes of melting and boiling and what ... 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.
