Why does a ceramic floor feel substantially colder to bare human feet than a wooden floor at the exact same room temperature?
Answer and explanation
Correct answer: A. the ceramic tile has a higher thermal conductivity than wood and conducts heat away rapidly
- Step 1: Both materials are at identical room temperature. Step 2. Sensation of cold depends on the rate of heat conduction away from the warmer foot. Ceramic tile conducts heat much faster due to higher thermal conductivity. Answer: the ceramic tile has a higher thermal conductivity than wood and conducts heat away rapidly. Why not the others: Both floors share equal temperature; wood does not emit latent heat; reflection of infrared does not explain contact conduction.
