== == 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.

= temperature at which (all of) a (pure) substance is boiling: going from liquid into gas (vaporous) phase
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.
Boiling point is affected by air pressure. Normal means measured at normal atmospheric pressure.
The point when water evaporates into water vapour.
The temperature at which a substance changes from liquid to gas
It's a physical property.
The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.
Helium
When a substance reaches its melting point it changes from solid to liquid. When a substance reaches its boiling point it changes from liquid to gas.
Each liquid boils at a different temperature, but the temperature it boils at is called the Boiling Point. For example, the boiling point of water is 212 Fahrenheit.This specific temprature is dependant on the pressureon the liquid at that time, as an example at ahigher temperatures the boiling point is higher.
It depends on the substance. For water the boiling point is 100 degrees celsius
what is the melting point and boiling point of substance
The boiling point of a substance is an example of a physical property of that substance.
Boiling point is a physical property not a chemical property.
Celsius is not a substance and so does not have a boiling point
The boiling point of a substance is the temperature at which it changes from liquid state to gaseous or vapor state.
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.
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.
The substances volume is affected by a boiling point
The boiling point is specific for each substance.
Every substance has their own boiling point.
If the substance's boiling point is lower than room temperature, it is probably a gas. If the boiling point is higher, it will be a liquid.
Below 100 °C.
