Emissivity
noun
The measure of a surface's ability to emit energy as thermal radiation compared to an ideal black body.
The emissivity of the material was calculated to determine its efficiency in heat transfer.
Often appears as...
- calculate emissivity
- emissivity coefficient
Usage tips
Formal
high emissivity, low emissivity, thermal emissivity

Pro Tip 1/3Technical Understanding
Emissivity is a key factor in thermal dynamics.
In heat transfer analysis, knowing the emissivity of materials enhances accurate predictions.
Pro Tip 2/3Contextual Application
It is often related to materials in construction, electronics, and thermodynamics.
Emissivity values vary between materials; metals generally have lower emissivity compared to non-metals.
Pro Tip 3/3Real-World Relevance
Understanding emissivity is vital in climate studies and energy conservation.
In solar panels, higher emissivity can improve heat retention.
