The Sun Sol’s temperature and density are very high Density - Sol has a density of 160,000or 150 times denser than water at the core. Temperature – Sol has a core temperature of approximately 15.6 million K. All most all the energy that is generated by the sun comes from the inner ¼ of Sol’s radius (the core is about 1.5% of the suns total volume). Energy production is limited to the inner ¼ of the sun because a very high temperature is required for nuclear reactions to take place. At the outer edge of zone were energy is generated the temperature has dropped from 15.6 million K to 8 million K. The temperature of the Sun has dropped to about 5600 K at the surface. Hydrogen makes up about 71% of all the matter at the surface and about 34% of all the matter at the core. <Why is there such a large difference in hydrogen concentration?> Energy Generation Processes. Possible answers to what process generates energy at the suns core: Combustion, Meteoritic

Unformatted text preview: Impacts or Gravitational Contraction. Nuclear Reactions: Terms you need to know to understand nuclear reactions. Nucleus contains protons and neutrons. Proton positively charged particle in the nucleus. Neutron particle in the nucleus that has a net charge of zero. Electron negatively charged particle the moves around the nucleus. Element a substance that cannot be broken down into a simpler compound. Ion positive and negative Isotopes a nucleus has different number of protons and neutrons- Tritium (isotope of hydrogen). 3 is the Mass number (total protons and neutron in nucleus) 1 is the Atomic number (number of protons in nucleus) The number of neutrons is the mass number minus the atomic number.- Deuteron (second isotope of hydrogen) What is the Mass number for Deuteron? 2 What is the atomic number for deuteron? 1...
