A student touches a metal chair and a wooden chair that have been sitting in the same room for hours. The metal chair feels colder. Why?
Correct Answer: A. Metal conducts heat away from the hand faster than wood does.
Both chairs are at the same room temperature, but metal feels colder because it conducts heat rapidly away from your skin. The human body maintains about 37°C, while the air and objects in the room are cooler. When you touch metal, its high thermal conductivity allows energy to flow quickly from your hand to the metal surface. That rapid transfer lowers the temperature of skin sensors, making the metal “feel” colder. Wood, a poor conductor, transfers heat much more slowly, so your hand retains warmth and perceives it as less cold. The difference in sensation is due to heat flow rate, not actual temperature difference between the two materials.
Why Other Options are Incorrect:
B. Density doesn’t determine how fast heat leaves your hand.
C. Both objects have similar internal energies at the same temperature.
D. Light reflection affects appearance, not thermal sensation.
