Liquids and Gases - Boiling Points (2024)

Boiling temperatures for common liquids and gases - acetone, butane, propane and more.

The boiling point of a substance is the temperature at which it changes state from liquid to gas throughout the bulk of the liquid. At the boiling point molecules anywhere in the liquid may be vaporized.

The boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure.

The boiling point at atmospheric pressure (14.7 psia, 1 bar absolute) for some common fluids and gases can be found from the table below:

Liquids and Gases - Boiling Points (2024)

FAQs

Do gases or liquids have higher boiling points? ›

Explanation: Among solids, liquids, and gases, solids typically have the highest boiling points.

What is boiling point of liquid and gas? ›

Only liquids have boiling points. It is the temperature at which the liquid boils and changes into gas at 1 atmosphere (or 760 mm Hg) pressure. Gases have no boiling points.

What is the boiling point of a liquid? ›

The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).

When a liquid changes to a gas at the boiling point? ›

Vaporization is the process of converting a liquid into a gas. It is also called evaporation. Since we know that the particles of a gas are moving faster than those of a liquid, an input of energy must be required for a liquid to become a gas.

Do different liquids have different boiling points? ›

Different substances have different vapor pressures and therefore different boiling points. This is due to differing intermolecular forces between molecules.

Which is hotter gas or liquid? ›

If you heat a liquid enough, it will change into the gas phase of matter. That's the hottest phase of matter. The gas phase of water is steam.

Does boiling turn liquid into gas? ›

Boiling is the term used to describe liquid turning into gas at a higher temperature than evaporation. Different liquids boil at different temperatures. You can see steam rising from boiling water as it is a mixture of water vapour and small droplets of water that make it visible.

Which liquid has the highest boiling point? ›

The compound with the highest boiling point is n-Pentane.

The boiling point of a liquid is the temperature at which its vapor pressure reaches equilibrium with that of the atmosphere. Because the intermolecular forces acting between the molecules of the liquid vary, different liquids have different boiling points.

What liquid has the lowest boiling point? ›

The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.

What is the boiling point of air? ›

The boiling point of air is −194.35 °C (78.80 K; −317.83 °F), intermediate between the boiling points of liquid nitrogen and liquid oxygen.

What is the boiling point of oxygen? ›

Oxygen is a colourless odorless diatomic gas with an atomic number 8 and atomic weight 15.999. It has a melting point of -219°C and a boiling point of -183°C 1.

Does the boiling point of a liquid increase? ›

The boiling point of liquid increases with increase in pressure.

What liquid turns into gas? ›

Vaporization is a process where a liquid changes to gas at its boiling point. Evaporation is a process where a liquid changes to gas at below its boiling point. For example- water has a boiling point of 100 Degree Celsius and heating water at 100 Degree C will be called Vaporization.

What is liquid to gas below boiling point called? ›

Evaporation is the change of liquid to the vapor state at any temperature below the boiling point of the liquid.

How a liquid changes to a gas without boiling? ›

A liquid can also change to a gas without boiling. This process is called evaporation. It occurs when particles at the exposed surface of a liquid absorb just enough energy to pull away from the liquid and escape into the air.

Which has more higher boiling point? ›

Xe has the highest atomic size and molecular weight. Hence, it has strong van der waal's forces of attraction. Hence, it has the highest boiling point.

Do gases have the lowest boiling point? ›

Every gas has the boling point. Substances considered as a (permanent) gas have their boiling point below the room temperature. The lowest boiling poist has helium-4, near 4.2 K.

Which has higher boiling point solid or liquid? ›

Solids have the highest boiling points because most amount of energy is required to break the bonds between the atoms in solids.

Which is stronger liquid or gas? ›

Flexi Says: Liquids generally have stronger intermolecular forces than gases. This is because the particles in a liquid are closer together than in a gas, allowing for stronger interactions between them.
