Quick Answer: What is a boiling point in chemistry?

boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature.

What is boiling point in chemistry short answer?

Physics, Chemistry. the temperature at which the vapor pressure of a liquid is equal to the pressure of the atmosphere on the liquid, equal to 212°F (100°C) for water at sea level.

What is boiling point in simple terms?

The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. … As an example, at sea level the boiling point of water is 100 C (212 F), but at 6,600 feet the boiling point is 93.4 C (200.1 F).

How do you explain boiling?

Boiling is the process by which a liquid turns into a vapor when it is heated to its boiling point. The change from a liquid phase to a gaseous phase occurs when the vapor pressure of the liquid is equal to the atmospheric pressure exerted on the liquid.

What is boiling point class 9th?

Boiling Point: The temperature at which the liquid boils and changes into gaseous state at the atmospheric pressure is called boiling point. For example, water boils at 100°C to form water vapour (at 76 cm pressure).

What is boiling point Class 12?

Boiling point is the temperature of a liquid at which its vapour pressure becomes equal to the atmospheric pressure.

How do you find boiling point?

The Formula for Boiling Point

It are often calculated as: Kb = RTb2M/ΔHv, R is that the universal gas constant. Tb is that the boiling temperature of the pure solvent [in K] M is that the molar mass of the solvent.

What determines boiling point?

Types of Molecules: the types of molecules that make up a liquid determine its boiling point. If the intermolecular forces between molecules are: relatively strong, the boiling point will be relatively high. relatively weak, the boiling point will be relatively low.

How do you determine boiling point?

A liquid’s boiling point can be determined using the capillary method, where an inverted capillary is placed in the liquid of interest and the liquid is heated. As the temperature increases, the air in the capillary escapes and is replaced by the vapor of the liquid.

What is the meaning of boiling in science?

Scientific definitions for boil

To change from a liquid to a gaseous state by being heated to the boiling point and being provided with sufficient energy. Boiling is an example of a phase transition.

What’s boiling in science?

In science, boiling happens when liquid becomes gas, forming bubbles inside the liquid volume. In cooking, water is the most frequently used liquid that is boiled. The temperature when water will begin to boil is around 212 degrees Fahrenheit/100 degrees Celsius. This is called the boiling point.

What is the significance of boiling point and melting point of a substance?

The boiling point is the temperature at which a material changes from a liquid to a gas (boils) while the melting point is the temperature at which a material changes from a solid to a liquid (melts).

What is boiling point short answer Class 9?

The temperature at which vapour pressure of a liquid becomes equal to the atmospheric pressure is known as boiling point.
