Gas vs. Vapor — What's the Difference?

A state of matter with no fixed shape or volume.

A visible mist or cloud of particles suspended in the air.

A substance in a form that fills its container.

The gas phase of a substance undergoing evaporation.

In physics, a vapor (American English) or vapour (British English and Canadian English; see spelling differences) is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature. A vapor is different from an aerosol.

A fluid substance with an ability to expand freely.

The gaseous state of a substance that is liquid or solid at room temperature.

Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma).A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g.

An aëriform fluid; - a term used at first by chemists as synonymous with air, but since restricted to fluids supposed to be permanently elastic, as oxygen, hydrogen, etc., in distinction from vapors, as steam, which become liquid on a reduction of temperature. In present usage, since all of the supposed permanent gases have been liquified by cold and pressure, the term has resumed nearly its original signification, and is applied to any substance in the elastic or aëriform state.

A complex mixture of gases, of which the most important constituents are marsh gas, olefiant gas, and hydrogen, artificially produced by the destructive distillation of gas coal, or sometimes of peat, wood, oil, resin, etc. It gives a brilliant light when burned, and is the common gas used for illuminating purposes.

Show off

The vapor you see is water turning into its gaseous state due to the heat.

Heating or reducing pressure can cause substances to evaporate or sublimate, turning into vapor.

Steam is the vapor form of water, so it's a type of gas.

Yes, all vapors are in the gaseous state, but not all gases are vapors.

The air is a mixture of gases, including oxygen, nitrogen, and trace amounts of other gases.

Most liquids produce vapors when exposed to certain temperatures, but the rate of vapor production varies.

No, many vapors are invisible. Visibility depends on factors like temperature and particle size.

Yes, gases can be turned into liquids under the right conditions of temperature and pressure.

Fog consists of tiny liquid water droplets suspended in the air, so it's closer to a vapor.

Natural gas, primarily methane, is easily combustible and efficient for cooking. It's a gas, not a vapor derived from a liquid.

Some vapors, like those from certain chemicals, can be harmful if inhaled.

Above the critical temperature, a substance cannot be liquefied, regardless of the pressure. It remains a gas, not a vapor.

Water vapor is gaseous water in the air, while moisture refers to the presence of liquid water, often on surfaces.

It depends on the substance's molecular properties and the ambient temperature and pressure.
