What is Volatile organic compound?
'''Volatile organic compounds (VOCs)''' are a type of [[gas]]es that can move through the air easily. They are [[organic compound]]s, which means they contain [[carbon]]. They have a high [[vapor pressure]], so they [[boiling point|become gas]] at a low temperature. Most [[scent]]s that we can [[olfaction|smell]] come from [[molecule]]s of VOCs. VOCs are often made through [[burning]]. For example, burning [[fossil fuel]]s makes VOCs. They are a common type of [[air pollution]]. High levels of VOCs in the air can affect [[breathing]], affect the [[immune system]], and cause [[allergies]]. They can also [[chemical reaction|react]] with other chemicals and make [[smog]].
