Study Notes
Heat Energy
- The main source of heat energy is the nuclear reactions that occur within the Sun's core.
- Heat energy is produced through the process of nuclear fusion, where hydrogen atoms combine to form helium, releasing vast amounts of energy in the form of light and heat.
- The increase in kinetic energy, resulting in warmth, is caused by the vibration of atoms and molecules, which is a result of the transfer of energy from the Sun's core to the Earth's surface.
