Varmaleiðni
Varmaleiðni, also known as thermal conductivity, is a material property that quantifies the ability of a substance to conduct heat. It is defined as the amount of heat that flows through a unit area of a material in a unit time, under a unit temperature gradient. The SI unit for thermal conductivity is watts per meter-kelvin (W/(m·K)).
Materials with high thermal conductivity are excellent conductors of heat, allowing heat to transfer quickly and
In practical applications, thermal conductivity is crucial in various fields such as engineering, materials science, and
The thermal conductivity of a material can be measured using various experimental techniques, such as the transient
In summary, varmaleiðni, or thermal conductivity, is a fundamental property that describes a material's ability to
