When a liquid changes to a gas below its surface as well as at the surface, the liquid is at a temperature equal to or greater than its boiling point.

The change of state from liquid to gas at the surface of a liquid is called evaporation. It occurs when the molecules at the surface of the liquid gain enough energy from the surroundings to escape into the gas phase.
False. Boiling occurs when a liquid changes to a gas at its surface due to the presence of sufficient heat. Heating below the surface does not lead to boiling; it only increases the temperature of the liquid.
True. When evaporating a liquid, heat is added to increase its temperature until it reaches its boiling point. At this temperature, the liquid changes to bubbles of gas below its surface, transitioning from a liquid to a gas phase.
Gas is formed from evaporation when a liquid changes into a gas state at a temperature below its boiling point. Evaporation is the process by which molecules escape from the surface of a liquid into the air as vapor.
Vaporization occurs through boiling, where a substance changes from a liquid to a gas at its boiling point, or through evaporation, where a substance changes from a liquid to a gas at below its boiling point, usually at the surface.
gas to liquid is condensation. think of when the steam condenses on a surface as it cools
