The heat transfer from one place to another takes place through

Land and sea breezes are the result of

The thermal conductivity of plastic foam is

If the length between the hot and cold ends of the solid is larger, the rate of flow of heat will be

If the temperature difference between hold and cold faces of the solids is greater, the rate of flow of heat will be

The heat from the fireplace reaches us directly in the form of waves called

Heat is transferred in solids by

Bad conductors are also called

The movement of cold air from the sea towards the land is called

The amount of heat that flows in unit time is called the heat's

When the quick transfer of heat is required through a body, we use
