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 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 plastics have a lower density than metals ANSWER DOWNLOAD EXAMIANS APP
Physics When hot liquid is poured into a thick glass tumbler, it cracks because glass : Has high temperature coefficient of expansion Has a very low specific heat Has low temperature coefficient of expansion Is a bad conductor of heat so only inner surface expands Has high temperature coefficient of expansion Has a very low specific heat Has low temperature coefficient of expansion Is a bad conductor of heat so only inner surface expands ANSWER DOWNLOAD EXAMIANS APP
