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.
301 exam-style questions on CIE IGCSE Physics 2.3 Transfer of thermal energy, covering 2.3.1a Thermal conductors and thermal insulators, 2.3.1b Explaining thermal conduction, 2.3.2 Convection, 2.3.3a Thermal radiation, 2.3.3b Surface colour and texture, 2.3.3c Rate of emission and absorption of radiation, and 2.3.4 Consequences of thermal energy transfer. Each one has a worked solution and a mark scheme showing where the marks go.
