Question

An aluminium piece and a wooden piece have been left in a room for a few hours. When you go and touch them the aluminium seems colder than wood. Select the correct option. Assume room temperature to be 25°.

(a) Both have the same temperature greater than 25°

(b) Aluminium has a greater temperature than wooden piece

(c) Aluminium has a lower temperature than wooden piece

(d) Both have the same temperature equal to 25°

I have been asked this question in an interview.

My question comes from Temperature and Heat in division Thermal Properties of Matter of Physics – Class 11

Answer 1

Correct option is (d) Both have the same temperature equal to 25°

The explanation: Both have been left in a room for a few hours, so both will have the same temperature as that of the room. The only reason aluminium feels colder is because it conducts heat away from our body faster than wood.
