Poor thermal conductor
WebThe chemical elements can be broadly divided into metals, metalloids and nonmetals according to their shared physical and chemical properties.All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metals; and have at least one basic oxide.Metalloids are metallic … WebThe thermal conductivity of bulk polymers is usually very low, on the order of 0.1 – 0.5 Wm1K1, which is due to the complex morphology of polymer chains. Why are polymers …

Web6 Answers. Because the air is a bad conductor of heat the soup stays hot longer: only the first layer of air touching the soup gets hot fast, and heat is not transmitted efficiently to the bulk of air. For soup, in contrast to thermos, evaporation cooling should also be considered.
