What does emissivity mean?
The measure of a material's ability to emit radiation, typically measured as a ratio of the emitted radiation to the absorbed radiation. It is a property of a material that determines how efficiently it radiates energy.
Example
"The emissivity of the new material was found to be significantly higher than the old one, resulting in a more efficient heat transfer."
