What is aerosol liquid?
An aerosol is a colloid of fine solid particles or liquid droplets, in air or another gas. Aerosols can be natural or artificial. Examples of natural aerosols are fog, forest exudates and geyser steam.
Does aerosol can have gas?
The most common form of aerosol can propellant is a liquefied gas like butane, isobutane, or propane. The gas is turned into liquid by pressurizing it within the can.

Aerosols containing higher amounts must go in checked baggage, and it is advisable to make sure that the container is tightly closed and protected so that the button is not pressed during the flight.
What is the type of aerosol?
The five most common classifications of aerosols are dust, fume, mist, smoke, and fog. Generally, dust describes large, solid aerosols. Fumes are small, liquid aerosols. Smoke describes small, solid aerosols.
What is solid and liquid aerosol?
These very small liquid droplets and solid particles are lightweight, so they can float in the air for a long time without falling to the ground; in other words, they are suspended in the air. When particulate matter is suspended in a gas, it is called an aerosol.

What is the difference between aerosols and gases?
Compared to aerosols, vapors and gases are negligibly small and their entrance into the blood stream through the lungs is by the mechanism of diffusion. Aerosols are much larger and vary widely in size. Their arrival into the lungs is dependent on size.

A second important human influence on climate is aerosols.
In addition to various natural sources, they are produced from sulphur dioxide emitted mainly by power stations, and by the smoke from deforestation and the burning of crop wastes.

Handy tip: Remember, the container itself must not be able to carry any more than 100 ml, so you won't get away with taking a larger aerosol on board and claiming it is only part full. These aerosols must be carried along with other liquids and gels in one transparent, re-sealable plastic bag.
Why are aerosols bad?
One of the dangers of aerosol cans is that they include potentially harmful preservatives in their composition. Xylene, neurotoxins, formaldehyde, and carcinogens can be found in the components of aerosol cans. These chemicals can have dangerous effects on plants, animals, and humans when released into the atmosphere.

Are clouds an aerosol?
Clouds usually form around tiny airborne particles called aerosols. Clouds are made of water droplets, ice crystals, or a mix of both. When the sun warms the surface of the Earth, water from oceans and lakes, soil, and plants changes from a liquid to a vapor. This process is called evaporation.

aerosol, a system of liquid or solid particles uniformly distributed in a finely divided state through a gas, usually air. Aerosol particles, such as dust, play an important role in the precipitation process, providing the nuclei upon which condensation and freezing take place.

Products contained in aerosol cans found in the home are often extremely flammable. In the event of a fire breaking out in your property, many aerosol spray containers subjected to higher temperatures can give rise to an explosion and significantly increase the severity of a fire.
Is smoke an aerosol?
But while smoke is an aerosol, it's very important to recognize that not all aerosols are smoke. If you have an aerosol generated by low temperature processes, like vaporization, it generates a liquid-based aerosol when these vapors are cooled down to form droplets.

What is aerosol made of?
Traditionally, most aerosols are made from steel, which is then coated in tin to stop rusting or reacting to the contents. This mixture of steel and tin is called tinplate. The tinplate is wrapped into a cylinder and then has a top and bottom welded on to keep it leakproof.
