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
