Pentane has often been taken as an indicator of lipid peroxidation. Our purpose in this study was to determine its normal concentration in the breath of healthy humans. Using a specific and sensitive gas chromatography-mass spectrometry technique pentane concentrations in breath were lower than 10 ...
Isopentane is a major component (sometimes 30% or more) of natural gasoline, an analog of common petroleum-derived gasoline that is condensed from natural gas. It has a substantially higher octane rating (RON 93.7) than n-pentane (61.7), and therefore there is interest in conversion from the...

What is neopentane's boiling point? Phase Changes: The three main phases of matter are solid, liquid, and gas. When one of these phases changes to another phase, that is called a phase change. For example, when a liquid changes to a gas, that is called vaporization. The temperature whe...
