== == The amount of force that is holding the molecules of the substance together (intermolecular forces). A lot of things factor into this, including: * Hydrogen bonding * Ionic interactions * Hydrophobic interactions * Van der Waals forces * Permanent dipole-dipole interactions The stronger the intermolecular forces are (per molecule), the higher the boiling point will be, as it will require a greater amount of heat energy to overcome the intermolecular forces that hold molecules in a liquid state.

The substance can't get any hotter.

The boiling point is the temperature where the vapor pressure is the same as the air pressure. It is the temperature where the bubbles can form, allowing the liquid to evaporate inside, not just at the surface.

Once the temperature reaches this point, all of the energy is put into spreading out the molecules of liquid into vapor. Because of that, none of the energy is used to raise the temperature. So, a boiling liquid cannot get any hotter.

Every liquid has its proper boiling point which is determined by density and other properties. Boiling point means that a liquid boils at a specific temperature. It is possible that two different liquids have the same boiling point.

When the temperature of a determined liquid starts to boil at 90ºC and start to become gaseous, the boiling point is caused when the temperature reaches 90ºC. Thus, to name such boiling point, the temperature at that moment is used. If different liquids are heated to become gaseous, and if only this moment is considered, the condition called "boiling point" hasn't any sense, because there is nothing associated to it. Then it is necessary to add any unit to make that point a named physical process. What would be the name? The temperature expressed as a number.

Does gases have a boiling point?

Gas is a phase of a substance. Boiling is the point when a substance chains from liquid to gas. So if it is already gas, it has already reached the boiling point.


What type of substance is a boiling point?

A boiling point isn't a substance at all. The boiling point of a substance is the temperature at which it changes from liquid to gas. For example, the boiling point of water at standard pressure is 100°C or 212°F. The boiling point of helium is -269°C or -452°F or 4.2K. The boiling point of iron is 2,862°C or 5,182°F.
