All power plants convert heat into electricity using steam. At nuclear power plants‚ the heat to make the steam is created when atoms split apart - called fission. The fission releases energy in the form of heat and neutrons. The released neutrons then goes on to hit other neutrons and repeat the process‚ hence generating more heat. In most cases the fuel used for nuclear fission is uranium. Most supporters of nuclear energy point out the low carbon emission aspect of nuclear energy aAlthough nuclear

The Identification and Production of Materials 1. Fossil fuels provide both energy and raw materials such as ethylene‚ for the production of other substances. Students Learn To: .2 Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum. • Ethylene is produced either from natural gas or crude oil‚ which are mixtures of hydrocarbons. One method involves… Cracking: a process by which hydrocarbons with higher molecular

period 3rd . The symbol for Scandium is Sc on the periodic table. Scandium is used for and is in many things. For example it is used to help grow crops such as corn‚ peas‚ and other seed grown plants. There are many protons and neutrons in Scandium. There are 21 protons‚ 24 neutrons‚ and 21 electrons. Scandium is also used in tracking devices. Scandium was discovered in Sweden 1879‚ by Lars Fredrick Nilson. Scandium was discovered when attempting to produce a sample of pure ytterbium from 10 kilograms

how reactors work‚ the environmental impact‚ and the health consequences of radiation exposure. As nuclear energy emerged‚ an Italian physicist‚ Enrico Fermi‚ discovered the power of nuclear fission in 1934 (Britannica). He blasted uranium with neutrons to create a product much lighter in comparison to uranium. During the 1950s and 1960s‚ nuclear power plants

The 5th state of matter INTRODUCTION Ice is transformed to water at 0°C when the energy of its molecules (particles) increases. Water is similarly transformed to vapor at 100°C (Fig.1). Much stronger zigzag motion of the particles separates and ionizes hydrogen and oxygen i.e. plasma comes into existence (above 13 000 K). Do all bodies fit one of these four states of matter? The answer is: no‚ e.g. the solar corona does not! Fig. 1 The temperature scale. It starts at 0K. Is it infinite long

process‚ two hydrogen nuclei fuse together and a deuterium nucleus‚ which has one proton and one neutron‚ is formed. A neutrino is created‚ too. Then‚ the deuterium nucleus fuses with another proton and forms the nucleus of helium-3‚ with two protons and one neutron‚ during which time a gamma ray photon is released. Finally‚ two helium-3 fuse together and create helium-4 with two protons and two neutrons. 3. How does the Sun manage to maintain an environment in its core that is conducive to nuclear
