Boiling in a liquid occurs throughout the entire volume of the liquid, as the heat energy applied causes the liquid to reach its boiling point temperature, at which the liquid's vapor pressure equals the external pressure. This results in bubbles of vapor forming within the liquid and rising to the surface.

Is it true that sublimation and boiling both happen at the surface of the substance?
No, sublimation occurs when a solid turns directly into a gas without passing through the liquid phase, while boiling occurs when a liquid turns into a gas. Sublimation can happen at the surface of a solid, while boiling happens within the liquid as bubbles of gas form throughout the substance.
What is it called the temperature at which a liquid boils?
The temperature at which a liquid boils is called its boiling point.
Do Sublimation and boiling both happen at the surface of the substance.?
Sublimation occurs when a solid transitions directly to a gas without passing through the liquid phase, typically at the surface of the solid. Boiling, on the other hand, occurs when a liquid transitions to a gas throughout the bulk of the liquid, not just at the surface.
How is evaporation and boiling different?
In both cases, a phase change from liquid to gas occurs.evaporation normally is associated with a slow process where the liquid molecules, usually on or near the surface of the liquid, gain sufficient energy to overcome atmospheric pressure and the intermolecular forces of the liquid and escape as individual molecules of gas.boiling is usually a more rapid process involving the addition of heat to the liquid until the temperature is = to the boiling point of the liquid. At this point, the vapor pressure overcomes atmospheric pressure and intermolecular forces. In this condition, the liquid molecules not only at or near the surface, but also those within the liquid bulk, begin to vaporize. The result is the familiar bubbles of a boiling liquid. The bubbles are, of course, gas bubbles that escape the liquid as they breach the surface.
The point at which a liquid changes to gas?
The point at which a liquid changes to gas is called the boiling point. It is the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure.
What process can happen when a substance changes from a liquid to a gas?
The phenomenon associated with the change of a substance from a liquid to a gas is called boiling. Of course, a liquid can also evaporate without boiling, which is slower and harder to observe.

What will happen to water at its boiling point at a given pressure?
Liquid water become gaseous water (vapors).
Which boils quicker liquid with high boiling point or liquid with low boiling point?
A liquid with a lower boiling point will boil quicker because it requires less energy to reach its boiling point compared to a liquid with a higher boiling point.
What is the boiling point of any liquids?
Boiling points vary from liquid to liquid.
What happens to the boiling point of a liquid solvent when a solid or liquid is dissolved in that liquid?
The boiling point is usually increased.
What is vaporization at the surface of a liquid that is not boiling?
Vaporization at the surface of a liquid that is not boiling is called evaporation. It is a process in which molecules of a liquid escape into the gas phase without the liquid reaching its boiling point. Evaporation occurs at temperatures below the boiling point of the liquid.
The difference between the boiling point of a liquid in pure state and the boiling point of the liquid in solution?
Boiling Point Elevation
What is it called the temperature at which a liquid boils?
The temperature at which a liquid boils is called its boiling point.
What might happen if enough energy is absorbed by liquid water?
If enough energy is absorbed by liquid water, it will eventually reach its boiling point and start evaporating into steam. This process is known as boiling and the water will undergo a phase change from liquid to gas.
What is boiling tubes used for?
A boiling tube is used for boiling a liquid in
How are evaportion and boiling different?
Evaporation occurs at the surface of a liquid at any temperature as long as the substance is a liquid. Boiling occurs throughout the liquid and occurs at the boiling point.
