On a day when the air temperature is 30 °C, why does a metal spoon feel colder than a wooden spoon at the same temperature?
Answer and explanation
Correct answer: A. Metal conducts heat away from the hand faster
Metal is a better conductor, so it removes heat from the skin faster, which feels colder.
Answer: Metal conducts heat away from the hand faster.
Why not the others: Metal is at a lower temperature than wood: both are at the air temperature. Wood has a higher specific heat capacity: that does not explain the feeling of cold. Metal reflects heat from the hand: reflection is not involved.
