Heat can be transfer from one object to another in three different ways that are conduction, convection, and radiation. What is conduction? You might have observed that a frying pan becomes hot when kept on a flame. It is because the heat passes from the flame to the utensil.

Milk is hot but the surrounding area is relatively cool. The heat from the glass of milk is gradually transferred to the particles of the surrounding area that are comparatively cool. Similarly, the surrounding area is warmer in comparison to the chilled water bottle. So, heat is gradually transferred from the surroundings to the bottle.

What is conduction?

The process by which heat transfers from the hotter end to the colder end of an object without the movement of the particle of that object is known as conduction.

Here the heat is getting a transfer to the egg when the pan is heated. The heat from the egg when it is being cooked also gets transfer to the spoon that you use. When you touch the spoon, the heat from the spoon gets conducted to your hand and you can get a burn. The materials which allow heat to pass through easily are called conductors

Examples of conductors

Copper, aluminum, and iron are good examples of conductors.

If you replace the steel spoon with a wooden spoon you will not feel hot at all. Why is it so, similarly you must have observed that a metallic pan for cooking has a plastic or wooden handle which prevents your hand from getting burnt? This is because wood does not allow heat to pass through it.

Insulators

The materials which do not allow heat to pass through them easily, are known as poor conductors of heat. Poor conductors are also known as insulators.

Examples of Insulators

Wood, plastic, ceramic even water and air are poor conductors of heat.
