Heat Transfer definitions Flashcards

Transfer of heat through direct contact between substances at different temperatures.

Indirect heat transfer via fluid movement, driven by temperature differences and buoyancy.

Indirect heat transfer through electromagnetic waves emitted by objects.

A material's ability to conduct heat, denoted by 'k', influencing heat transfer rate.

Rate of heat transfer per second, often measured in watts.

An idealized object that emits maximum thermal radiation at a given temperature.

A measure of how closely a material emits thermal radiation compared to a blackbody.

Describes radiative heat transfer, stating power radiated is proportional to temperature to the fourth power.

Power emitted per unit area from an object's surface, measured in watts per square meter.

Power per unit area received at a distance from the emitting source.

An infinite source or sink of heat that maintains constant temperature despite heat exchange.

Waves of electric and magnetic fields, including visible light, that transfer energy.

The distance between successive peaks of a wave, influencing its color in visible light.

The number of wave cycles per second, determining the color of light.

Relates the peak emission wavelength of a blackbody to its temperature.
