Because at standard temperature and pressure carbon dioxide is a gas, the carbon dioxide sublimes and instantly produces a gas, condensing water vapor and creating a thick white fog. Liquid nitrogen (N 2) can be used in a similar manner to dry ice. In either case, a fan placed at the top of the container directs the fog where it is needed.
Dry ice in water. Liquid carbon dioxide (CO 2), stored in compressed cylinders, is used in conjunction with theatrical fog machines to produce "low-lying" fog effects. When liquid CO 2 is used to chill theatrical fog, the result is a thick fog that stays within a few feet of the ground. As the fog warms, or is agitated, it rises and dissipates.
An artificial opacifying fog triggered remotely to scare off burglars. Artificial fog is man-made fog that is usually created by vaporizing a water- and glycol- or glycerine-based fluid. The fluid is injected into a heated metal block which evaporates quickly. The resulting pressure forces the vapor out of a vent.
Mist and fog are aerosols. An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas. [1] Aerosols can be generated from natural or human causes.The term aerosol commonly refers to the mixture of particulates in air, and not to the particulate matter alone. [2]
The fluid used in haze machines to generate the effects are either oil or water-based. Most oil-based haze fluids use a mineral oil base, while water-based fluids use either a propylene glycol or glycerol base. Although both formulations of fluid are referred to as haze fluid, the different formulations are neither compatible nor interchangeable.
Smog, or smoke fog, is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a portmanteau of the words smoke and fog [ 1 ] to refer to smoky fog due to its opacity, and odor. [ 2 ]
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...
Nicknames include frozen smoke, [57] solid smoke, solid air, solid cloud, and blue smoke, owing to its translucent nature and the way light scatters in the material. The lowest-density silica nanofoam weighs 1,000 g/m 3 , [ 58 ] which is the evacuated version of the record-aerogel of 1,900 g/m 3 . [ 59 ]
