Estimating thermal conductivity of benzene
WebMar 15, 1989 · Abstract. New, absolute measurements of the thermal conductivity of the moderately polar liquid, chlorobenzene, are reported for four isotherms in the temperature range 308–360 K for pressures up to 430 MPa. The results have an estimated accuracy of ±0.3%. The density dependence of the thermal conductivity is found to be represented … WebMaterials with a high thermal conductivity constant k k k k (like metals and stones) will conduct heat well both ways; into or out of the material. So if your skin comes into contact with metal that is colder than your skin …
