A stone floor feels cold to the bare feet but a carpet on the same floor feels warm. This is because

  • A.The floor and carpet are at different temperatures
  • B.The stone conveys the heat away from the feet more rapidly than the carpet
  • C.The carpet is a better conductor of heat than the stone
  • D.The human body maintains a constant temperature

Answer: B

Because the stone conducts heat away from the feet more rapidly.

Both the floor and the carpet are at room temperature. Stone is a good conductor and draws heat from the skin quickly, which the nerves register as cold; the carpet is a poor conductor and traps air, so it removes heat slowly and feels warm.
