Physics On a cold day when a room temperature is 15oC, the metallic cap of a pen becomes much colder than its plastic body, though both are at the same temperature of 15oC, because plastics have a higher thermal conductivity than metals metals are good conductor of heat metals have higher thermal capacity than plastics plastics have a lower density than metals plastics have a higher thermal conductivity than metals metals are good conductor of heat metals have higher thermal capacity than plastics plastics have a lower density than metals ANSWER DOWNLOAD EXAMIANS APP
