Physics A stone floor feels cold to the bare feet but a carpet on the same floor feels warm. This is because The human body maintains a constant temperature The floor and carpet are at different temperatures The stone conveys the heat away from the feet more rapidly than the carpet The carpet is a better conductor of heat than the stone The human body maintains a constant temperature The floor and carpet are at different temperatures The stone conveys the heat away from the feet more rapidly than the carpet The carpet is a better conductor of heat than the stone ANSWER DOWNLOAD EXAMIANS APP
Physics When hot liquid is poured into a thick glass tumbler, it cracks because glass : Has low temperature coefficient of expansion Is a bad conductor of heat so only inner surface expands Has a very low specific heat Has high temperature coefficient of expansion Has low temperature coefficient of expansion Is a bad conductor of heat so only inner surface expands Has a very low specific heat Has high temperature coefficient of expansion ANSWER DOWNLOAD EXAMIANS APP
Physics Fish and other aquatic creatures can live inside a deep frozen pond because There will always be water just beneath the ice level They can adapt themselves to live in ice Ice is a bad conductor of heat Fish are cold-blooded animals There will always be water just beneath the ice level They can adapt themselves to live in ice Ice is a bad conductor of heat Fish are cold-blooded animals ANSWER DOWNLOAD EXAMIANS APP
