The thermal conductivity of a cloth is a measure of its capacity to a selected materials conduct warmth. It’s generally denoted by
ok
ok,
λ
lambda , or
κ
kappa .
Warmth switch happens at a decrease charge in supplies of low thermal conductivity than in supplies of excessive thermal conductivity. As an example, metals usually have excessive thermal conductivity and are very environment friendly at conducting warmth, whereas the alternative is true for insulating supplies like Rockwool or Styrofoam. Correspondingly, supplies of excessive thermal conductivity are broadly utilized in warmth sink purposes, and supplies of low thermal conductivity are used as thermal insulation. The reciprocal of thermal conductivity is named thermal resistivity.
