Physics A stone floor feels cold to the bare feet but a carpet on the same floor feels warm. This is because The floor and carpet are at different temperatures The human body maintains a constant temperature The carpet is a better conductor of heat than the stone The stone conveys the heat away from the feet more rapidly than the carpet The floor and carpet are at different temperatures The human body maintains a constant temperature The carpet is a better conductor of heat than the stone The stone conveys the heat away from the feet more rapidly than the carpet ANSWER DOWNLOAD EXAMIANS APP
