Energy can be transferred in three different ways

Energy Transfer

Energy can be transferred in three different ways. They are conduction, convection, and radiation.

1. Conduction is when heat is transferred through solid objects. When you place a pot on top of a stove, heat is transferred from the stove to the pot and that is conduction.

2. Convection is when heat is transferred through the flow of material. Convection is happening in the atmosphere, when the cool air pushes the warm air upward. Also when you are boiling water, there are convection currents in the water because the water is circulating throughout the water.

3. Radiation is when heat is transferred in the form of rays or waves. The sun’s sunlight is a form of radiation because it is transferred in the form of rays to Earth. Also when you put your hand near a hot stove, the radiation of the stove warms the surface of it.
