Do organic substances have high boiling points? Organic compounds have relatively low melting points and boiling points. … Since the attractive forces between molecules are weak, it doesn’t take much energy to disrupt them and thus organic molecules have low melting and boiling points.
What is the definition of melting point and boiling point? The main difference between boiling point and melting point is that the melting point is defined as the temperature at which solid and liquid phases are in equilibrium, whereas the boiling point is the temperature at which the vapour pressure of a liquid is equal to the external pressure.
What is boiling point short answer? boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature. boiling.
What is a melting point answer? melting 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.
