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.
decrease, but by a factor different from 3/2

(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. What is the conductive heat transfer under steady-state conditions? (2) The Born energy EB (SI unit kcal/mol) is a measure of...
please help Question 23 (1 point) Which observation is NOT explained by the intermediate disturbance hypothesis In the interior of an old forest a low number of K-type species dominate the community Species evenness is larger when disturbances are extremely frequent Species richness increases immediately after a disturbance such as a fire, but may decrease later In beach dune environments, a low number of r-type species dominate the community Question 24 (1 point) Some birds follow moving swarms of army...
I need help to write a nice introduction for experiment 6 please ( no hands write ) typing Thank you HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...
