Concrete specific heat
WebMay 22, 2024 · The moisture content has a great impact on the specific heat capacity of concrete at temperatures below 200°C due to vaporization. Thermal conductivity The thermal conductivity λ is defined as the rate at which heat flux passes through a unit area of homogenous material of unit thickness for a temperature difference of 1 K: WebTemperature (T) = 80.0 K. Specific heat (c) = 1676 KJ. Now we have to convert the specific heat into Joules because it is in Kilojoules. So, the conversion is like this. 1 KJ = 1,000 J. So, 1676 KJ = 1,000 × 1676 = …
