WebMay 22, 2024 · Thermal Conductivity of Polyurethane Foam. Thermal conductivity is defined as the amount of heat (in watts) transferred through a square area of material of given thickness (in metres) due to a difference in temperature.The lower the thermal conductivity of the material the greater the material’s ability to resist heat transfer, and … WebSpecific heat is closely related to the concept of heat capacity. Heat capacity is the amount of heat necessary to change the temperature of a substance by 1.00 °C . In equation form, heat capacity C is C = m c, where m is mass and c is specific heat. Note that heat capacity is the same as specific heat, but without any dependence on mass. WebApr 9, 2024 · Results also shows that the specific heat capacity and the thermal resistance varied in the opposite direction. As an example, the adding 40% of EPA aggregate to the concrete mixture gives an increase for about 44% in specific capacity and a reduction for about 32% in thermal conductivity .
