### gas:

Acid gas
* are gases which form acids in water.
* contribute to the acid rain that damages lakes and harms forests and buildings.

Acidic gas
* Most acidic gases cause damage
  - lung damage
* Some acidic gases cause corrosion.
* can permanently discolor painted surfaces.

Arsine
* are among the most toxic gases.
* reacts violently with oxidizing agents , such as the halogens.
+ Arsine, Properties: Arsenic compounds
  * It has a weak garlic odor. It easily burns to make arsenic trioxide in excess air or arsenic in small amounts of air. It breaks down to arsenic and hydrogen when heated. It can dissolve in water. It is heavier than air. Arsine reacts violently with oxidizing agents, such as the halogens.

Blood gas
* Some blood gas analyses prevent diagnoses.
* impedes the normal production and propulsion of oxygen through the blood stream.

Bottled gas
* are gases.
* is liquid because it is under pressure
  - used in the kitchen and fed from bottles

Cold gas
* can burn the skin as well as the lips and throat.
* provides the fuel for star formation.

Corrosive gas
* can also attack and corrode metals.
* can cause rapid destruction of skin and eye tissue
* combined with condensation can cause severe corrosion problems.
* require regulators designed specifically for the gas type.

Dangerous gas
* Some dangerous gases come from cars.
* are present near the pit surface.

### gas:

Different gas
* absorb at different wavelengths of light, referred to as transitions
  - infrared radiation at very different rates
* are present at different altitudes in Jupiter's atmosphere.
* comprise particles with different masses.
* emit and absorb at different characteristic wavelengths
  - other colours
* es produce different colors when excited.
* glow different colours.
* have different abilities to retain heat from the sun.
* make different colors.
+ Neon lamp: Lamps
  * A 'neon lamp' is a light bulb that can make many colors when Noble gasses are inside of the bulb. For example, helium would give a light yellow color and neon would make a red or orange color when an electric current is run in the tube. It is normally used to make letters for signs. Different gases make different colors. Neon Lamps are used to make neon signs.

Dissolved gas
* are brought to cells and enter the cells via simple diffusion
  - in equilibrium with the gas in the atmosphere
* play an important role in theories of gases.

Ethene
* is an olefin
* produces ripening in fruit, but also inhibits growth in plants.

### gas | ethene:

Trichloroethylene
* is an ethene
* takes effect slowly.

Flammable gas
* Most flammable gases have explosive ranges greater than flammable liquid vapors.
* Some flammable gases use for light.
* can mix with air causing fires and explosions.
* create the potential for fire or explosion.
* start being evolved in a process similar to dry distillation.

Fuel gas
* All fuel gases produce more heat and higher flame temperature when combined with oxygen.
* Every fuel gas has variation in properties, including temperature and BTU delivery.

Gas welding
* can result in explosions.
* uses an oxy-acetylene flame to heat the metal and a rod of metallic filler material.

### gas | greenhouse emission:

Chlorofluorocarbon
* absorb infra-red radiation more effectively than water vapour.
* are a group of organic chemicals containing carbon, fluorine, and chlorine
  - greenhouse gases
  - the source of most of the chlorine in the stratosphere
* cause ozone depletion and are minor greenhouse gases.
* contain carbon, chlorine and fluorine atoms
  - chlorine, one of the major destroyers of ozone
* deplete the ozone layer , which absorbs UV radiation.
* destroy the earth's protective ozone layer
* greenhouse emission
* is fluorocarbon
* move up to the stratosphere gradually over several decades.
* result from the synthesis of fertilizers.
