Vapour is a substance diffused or suspended in the air, especially one normally liquid or solid. A vapour is produced when a substance undergoes vaporisation, which simply implies heating up a liquid until it turns into vapour.
According to different sources, vapour โis a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapour can be condensed to a liquid by increasing the pressure on it without reducing the temperature.โ In other words, vaporising a liquid will alter its state, but vapour will comprise the same molecules as the substance in its liquid phase. Now technically, what is produced when we vape isnโt vapour at all, but aerosol. Since just about every vaper uses the (slang) term โvapourโ and not the scientifically precise term โaerosol,โ weโre going to stick with โvapourโ too.
When using a vape the smoke you exhale is called vapour and it is not the same as the smoke that is being exhaled while using traditional cigarettes. Vapour is not harmful for others, it does not have an unpleasant smell.
Lighting a cigarette will produce smoke, while vaporising e-liquid will produce vapour (aerosol). Outside of their visual similarities, smoke and vapour donโt have much in common. They are very different in composition, and behave in very distinct ways. Hereโs how these substances differ to each other in a nutshell.
When it comes to tobacco and e-liquid, the only thing they have in common is nicotine. Tobacco smoke contains thousands of chemicals, with 70 of them being proven carcinogens and many more being unhealthy to inhale.
Althoughย vapes do not produce water vapour, vaporised e-liquid comprises of vegetable glycerin, propylene glycol, nicotine, and food grade flavourings. With the exception of nicotine, everything thatโs included in e-liquid is safe to ingest, according to the CDC. Safety for inhalation has not been proven, but neither has risk. The science is still coming in.
The smell of smoke lingers in the room for a long time, unlike vapour. Smokers might not notice it that easily, but vapers and non-smokers can recognise the smell in a closed room for hours after a cigarette has been smoked.
Vapor clouds might be denser and dissipate slower โ i.e., stay visible in the room for a longer time โ but the smell will be much more pleasant and go away much more quickly.
Smoking inside a room will eventually stain fabrics, walls, and furniture. One of the culprits behind that is tar, the toxic resinous mixture that makes smoking so deadly, and is also notorious for staining everything it comes in contact with. Other byproducts of combustion, such as carbon monoxide, will work alongside tar to give your walls this dirty, yellow tint.
Theย PG and VGย in vapor may create a thin, blurry coating on glass surfaces, but it cleans up easily. It will not turn your walls and fabrics yellow over time and wonโt make furniture look older than it actually is.
The temperature of the cigarette coal is around 1112 F (600 C) when resting, rising to 1652 F (900 C) when taking a puff. While smoke rapidly reaches room temperature when inhaled and exhaled (mainstream smoke), the smoke that gets produced on the coal itself (sidestream smoke) will raise the peripheral temperature, especially when the cigarette is becoming smaller.
E-cigarettes, on the other hand, vaporize e-liquid at much lower temperatures, usually not higher than 482 F (200 C). As a result, the exhaled vapor is much cooler, coming out at a temperature lower than the surrounding room air. Try exhaling on your arm, and youโll see for yourself.
