A liquid with a low boiling point indeed changes to vapor more readily than one with a high boiling point when exposed to heat. The boiling point of a liquid is the temperature at which its vapor pressure equals the atmospheric pressure, allowing it to transition from the liquid phase to the gas phase. Liquids with lower boiling points have higher vapor pressures at a given temperature compared to those with higher boiling points. This means that as heat is applied, the molecules in a low boiling point liquid gain enough energy to overcome intermolecular forces more easily, enabling them to escape into the vapor phase sooner than liquids with high boiling points. Thus, the statement is true, showcasing the relationship between boiling point and the rate of vaporization.
