The temperature at which a liquid changes to a gas is BEST described as:

Explanation:
The boiling point is the temperature at which a liquid changes into a gas. At this point the liquid’s vapor pressure equals the surrounding pressure, so vapor forms not just at the surface but throughout the liquid. This is different from evaporation, which can happen at any temperature but only from the surface. The other terms describe different transitions: freezing point is liquid to solid, melting point is solid to liquid, and condensation point is gas to liquid. So, for a liquid turning into a gas, the boiling point is the appropriate descriptor. For reference, water boils at 100°C (at sea level).
