Question

If an iron chair and a wooden chair are kept in the sun for a sufficient amount of time and then, are touched, which of them will appear warmer?

• A. Iron chair
• B. Wooden chair
• C. Both will appear equally warmer
• D. Depends on the temperature of the surroundings

Answer 1

The correct option is A

Iron chair

When an iron chair and a wooden chair are kept in the sun for a sufficient amount of time, both acquire the same temperature, which is equal to the temperature of the surrounding. But the rate of heat transfer is faster in a metal chair because metals are good conductors of heat and wood is a bad conductor of heat. Hence, the metal chair will appear warmer than the wooden chair when we touch them.
