On a cold winter morning, a person steps with one bare foot on a ceramic tiled kitchen floor and the other bare foot on a woolen rug. Although both the tiles and the rug are at the exact same room temperature, the ceramic tiles feel significantly colder to the person's feet. Why is this?
The ceramic tile has a higher specific heat capacity than the wool rug.
The ceramic tile absorbs more infrared radiation than the wool rug.
The ceramic tile is a better thermal conductor than the wool rug.
The ceramic tile has a lower density than the wool rug.
