Outdoors on the winter, why does a piece of metal feel colder than piece of wood

Concept:

There are three methods of heat transfer between the two systems. They are conduction, convection, and radiation.

• Conduction is a method of heat transfer in solids and heat transfer takes place without the movement of particles.
• Convection is a method of heat transfer in fluids (gases and liquids) and heat transfer takes place due to the movement of particles.
• Radiation is a method of heat transfer where heat is transferred from one place to another without affecting the medium of heat transfer.

Explanation:

• Both are at the same temperature, the metal will feel colder than the wood because of the thermal conductivity of the metal, compared to the wood is more.

Metal will conduct the heat faster than wood to your hand.

The specific heat capacity of wood is much higher than iron. Hence it takes time to get cooler or hotter compared to metal.
