Unit Two: Energy

Summary • Heat energy: One of the energy forms transfers from higher temperature to lower temperature. • Temperature: It is the heat condition which states whether heat transfers from or to an object when it comes in contact with another. And it is proportional to the kinetic energy of the particles. • Ways of heat transfer: 1. Heat transfers by conduction. 2. Heat transfers by radiation (does not need any material medium). 3. Heat transfers by Solar furnace convection. • Technological applications which produce heat: 1. Heater. 2. Water heater. 3. Stove. 4. Ovens. The origin of most of energy resources and its forms on earth is solar energy.
