Because few materials exhibit the needed properties at room temperature, applications have so far been limited to cryogenics and research.

Because rhodium metal is inert against corrosion and most aggressive chemicals, and because of its rarity, rhodium is usually alloyed with platinum or palladium and applied in high-temperature and corrosion-resistive coatings.

Because tungsten is rare and its compounds are generally inert, the effects of tungsten on the environment are limited.

Because the various binders and inert ingredients that were contained in the pill form were toxic when smoked, this practice was roundly decried by the medical community as a serious health risk.

Because plutonium is chemically reactive it is common to plate the completed pit with a thin layer of inert metal, which also reduces the toxic hazard.

Because of their common use in preservation, it is usually desirable for a desiccant to be substantially chemically stable or chemically inert, and a number of useful desiccants with this property have been identified and are in common use, such as silica gel, chalk and clay-based desiccants.

Because of their inert nature, medical grade Silastic brand silicone elastomers are important materials in numerous medical and pharmaceutical devices including catheters, pacemaker leads, tubing, wound dressings and silos for abdominal wall defects.

Because it is a clean and non-contact process it can be used in a vacuum or inert atmosphere.

Because it is softer than most other metals in general use, brass is often used in situations where it is important that sparks not be struck, as in fittings and tools around explosive gases.

Because of its magnitude, scientists formerly speculated that the gases released during the formation of the Deccan Traps played a role in the Cretaceous – Paleogene extinction event ( also known as the K-Pg extinction ), which included the extinction of the non-avian dinosaurs.

Because the GWP of a greenhouse gas depends directly on its infrared spectrum, the use of infrared spectroscopy to study greenhouse gases is centrally important in the effort to understand the impact of human activities on global climate change.

Because metals burn without releasing cooling gases, they can potentially burn at extremely high temperatures.

* Because the vacuum removes various gases ( e. g. O < sub > 2 </ sub >, CO ) and liquids ( e. g. water, alcohol, solvents ) that were initially trapped within or on the surface of the sample, the chemistry and morphology of the surface will continue to change until the surface achieves a steady state.

Because gases are expelled but not admitted this creates a slight vacuum in the crankcase so that any weak joint or failed seal causes air to be sucked in rather than allowing oil to leak out.

Because of its design, its high temperatures allow higher thermal efficiencies than possible in traditional nuclear power plants ( up to 50 %) and has the additional feature that the gases do not dissolve contaminants or absorb neutrons as water does, so the core has less in the way of radioactive fluids.

Because the valve stem extends into lubrication in the cam chamber, it must be sealed against blow-by to prevent cylinder gases from escaping into the crankcase, even though the stem to valve clearance is very small, typically 0. 04-0. 06 mm.
