Emit vs. Exhaust: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Updated on November 13, 2023
Emit refers to producing or sending out something like light, sound, or energy. Exhaust means to use something up completely or to drain of energy.

Key Differences

Emit typically refers to the release of substances or forms of energy (like light, sound, heat) from a source, often in a controlled or natural manner. Exhaust, on the other hand, often implies the expelling of gases or steam, usually as a byproduct of a process (like in engines) or to describe a state of being used up or depleted of resources or energy.
