Dew point is the highest temperature at which airborne water vapor will condense to form liquid dew.

Tear gas, formally known as a lachrymatory agent or lachrymator (from the Latin lacrima, meaning "tear"), is a chemical weapon that causes severe eye, respiratory, and skin irritation, pain, vomiting, and even blindness.

The kinetic theory describe a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container.

Vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system.

Silane is an inorganic compound with chemical formula, SiH4, making it a group 14 hydride.

Breathing is the process that moves air in and out of the lungs, or the diffusion of oxygen and carbon dioxide to and from the external environment into and out of the blood through other respiratory organs such as gills.

Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.

In thermodynamics, the Joule–Thomson effect (also known as the Joule–Kelvin effect, Kelvin–Joule effect, or Joule–Thomson expansion) describes the temperature change of a real gas or liquid (as differentiated from an ideal gas) when it is forced through a valve or porous plug while kept insulated so that no heat is exchanged with the environment.

In thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve.

An inert gas is a gas which does not undergo chemical reactions under a set of given conditions.

Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and very often some carbon dioxide.

In chemistry, absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – gas, liquid or solid material.
