Butane (/ ˈ b juː t eɪ n /) is an alkane with the formula C 4 H 10. Butane exists as two isomers, n -butane with connectivity CH 3 CH 2 CH 2 CH 3 and iso-butane with the formula (CH 3 ) 3 CH . Both isomers are highly flammable, colorless, easily liquefied gases that quickly vaporize at room temperature and pressure.

In general, gas condensate has a specific gravity ranging from 0.5 to 0.8, and is composed of hydrocarbons such as propane, butane, pentane, and hexane. Natural gas compounds with more than two carbon atoms exist as liquids at ambient temperatures and pressures. [4] Propane, butane, and isobutane are
Canned goods that freeze can present health risks, according to the U.S. Department of Agriculture. USDA says cans can swell if the food inside expands when its frozen — or because of a bacteria ...
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
