coefficient of thermal conductivity

The coefficient of thermal conductivity is a physical quantity that expresses the ability of a material to transfer heat. Specifically, it determines how heat passes through the given material and at what speed. In practice, the coefficient of thermal conductivity is denoted by the symbol "λ" and is expressed in units of W/m·K (Watts per meter per kelvin).

A higher coefficient of thermal conductivity means that the material is a good conductor of heat, which means that heat passes through it faster. Conversely, a lower coefficient of thermal conductivity means that the material is a poor conductor of heat and heat is transferred through it more slowly.

The coefficient of thermal conductivity is an important parameter in the design and installation of insulation materials, heating and cooling systems and other applications where it is important to regulate heat transfer. When insulating buildings, materials with a low coefficient of thermal conductivity are used to minimize heat loss and improve energy efficiency.

When choosing materials and designing thermal systems, it is necessary to take into account the values of the coefficient of thermal conductivity in order to achieve the required level of thermal insulation and efficient use of heat in a specific environment.
