Answer #1

Tiles are better thermal conductor than wood. When we put our foot on tile, heat is transferred readily, that's why tiles feel colder. While heat transfer from foot to wood floor will take more time, because of less heat conductivity, that's why woods feel warmer.

Tile has larger thermal conductivity than wood.

    (1) A pig lying on a 2.0 cm thick wood floor has its belly in contact with the floor. Let the contact surface area of pig's belly and floor floor be 3000 cmn'. The floor is cooler than the pig's body temperature (30°C), and at a temperature of 0.0 °C. The thermal conductivity of wood is 0.126 W/m °K.
