Question

A piece of wood and a piece of steel are at the same temperature; however, the steel feels hotter. This is because the steel has _____.
A- more entropy
B- greater thermal conductivity
C- greater thermal insulation
D- a higher R-value

Answer 1

B- Greater thermal conductivity

Answer 2

Answer: The correct answer is "greater thermal conductivity".

Explanation:

Thermal conductivity: It is a ability to conduct heat. Heat transfers occur at a lower rate to material at higher thermal conductivity.

It is defined as the rate at which the heat is transferred through a unit thickness of the substance per area per change in the temperature.

In the given problem, A piece of wood and a piece of steel are at the same temperature. However, the steel feels hotter. The thermal conductivity of the steel is more than the thermal conductivity of the wood.

Therefore,  the correct option is "greater thermal conductivity".
