A parograph about energy.

Scientists saw that there was energy in objects. Radiation is the transfer or passage of energy. Radiation doesn't need matter to pass energy. For example, it's winter and while reading a book on the couch there is a feeling of warmth with the heater radiating heat into the air. That is radiation.The energy is being transfered to the body. Convection is taking heat from one area to another. One example of convection is just like hot water in a pot and rises to the top with water vapor. Finally, conduction, the tranfer of heat by touching an object. An example of conduction is a cold spoon in a large hot bowl. Radiation, convection, and conduction are everywhere. In weather, a house, even cooking, these transfers of heat warm everything in the world.
