33. On a cold day when the room temperature is 15°C, the metallic cap of a pen becomes much colder than its plastic body, though both are at the same temperature of 15°C, because : A.Metals have higher thermal capacity than plastics B.Plastics have a lower density than metals C.Metals are good conductors of heat D.Plastics have a higher thermal conductivity than metals
Option C Solution: On a cold day when the room temperature is 15°C, the metallic cap of a pen becomes much colder than its plastic body, though both are at the same temperature of 15°C, because metals are good conductors of heat.
