Mass and energy Mass and energy Einstein suggested that mass and energy are related by E=mc 2 (c = 3.0 x 10 8 m/s) E: energy, m: mass, c: speed of light Converting the mass of one penny could provide the entire energy requirements for 700 people for one year Power a space heater for 7000 years That’s about $3 million worth of electricity Because mass and energy are related the law of conservation of energy and law of conservation of mass can be combined into the Law of Conservation of Mass - Energy

Fission and Fusion Fission and Fusion Chemical reactions involve outer electrons Nuclear reactions involve changes in nuclei Two types of nuclear reactions are fusion and fission (others are radiation and transmutation) Fission is when a nucleus breaks apart Fusion involves adding nucleons to a nucleus Fission is used in nuclear power plants and powered the first atomic bomb (21 kilotons) Fusion powers stars and may also be used in thermonuclear bombs (60 megatons) Fusion requires that the nucleons be close
