More About Emission
What doesemission mean?
An emission is something that has been emitted—released or discharged. In general, emissions consist of things like gas, liquid, heat, sound, light, and radiation.
Emissions can come from natural sources or from machines. A specific example of an emission is the exhaust from cars (in the U.S., such emissions are regulated through emissions tests). This exhaust is just one form of carbon emissions—greenhouse gases from various sources that are known to contribute to global warming and climate change.
Emission can also refer to an instance or the process of emitting, as in This filter is designed to reduce the emission of light.
Example: Carbon dioxide emissions from volcanoes are much lower than those from cars and airplanes.
Where doesemission come from?
The first records of the word emission come from the early 1600s. It ultimately derives from the Latin verb ŧٳٱ, from e-, meaning “out of,” and mittere, “to send.”
An emission is something sent out from something else. Such emissions are often by-products released during the course of other processes—such as smoke being emitted from a factory or heat being emitted from a machine. Emissions from cars and airplanes come from the burning of fuel by their engines. In physics and electronics, the word is used in a more specific way to refer to the amount of electrons being emitted from an object.
