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 lower density than metals metals have higher thermal capacity than plastics metals are good conductor of heat plastics have a higher thermal conductivity than metals plastics have a lower density than metals metals have higher thermal capacity than plastics metals are good conductor of heat plastics have a higher thermal conductivity than metals ANSWER DOWNLOAD EXAMIANS APP
Physics In very cold countries alcohol is used as a thermometric liquid because Its freezing point is very low Alcohol can be coloured for its level to be seen easily It will not stick to the glass tube Alcohol is a poor conductor of heat Its freezing point is very low Alcohol can be coloured for its level to be seen easily It will not stick to the glass tube Alcohol is a poor conductor of heat ANSWER DOWNLOAD EXAMIANS APP
