    “The evolution of the world can be compared to a display of fireworks that has just ended; some few red wisps‚ ashes and smoke. Standing on a cooled cinder‚ we see the slow fading of the suns‚ and we try to recall the vanishing brilliance of the origin of the worlds.” (Four Pillars‚ n.d.) The Big Bang theory is perhaps the greatest discovery of all time. The Big Bang is a cosmological model that explains how the universe came to be and is based on known and well-tested laws of physics. However

    Saturn produces its only heat and light energy by the friction of the helium rain which can be found in the atmosphere. It has a pale yellow colour because of the ammonia crystals which can be found in the outer atmosphere as well. It has a low surface gravity because it does not have a solid surface like Earth. Its rings

    Name: Salathiel R. Wells Date: 14th July 2011 English Commentary Feet September 1948 The extract ‘Feet’ taken from Reading in the Dark (1996) explores the concept of childhood‚ an excelled level of maturity‚ neglect‚ fear as a dominant mood and the significance of “feet”- using it as a synecdoche to represent people. The writer conveys his message further through the use of imagery and many literary features namely: metaphors‚ repetition and personification. The extract

    many electrons do you suppose that bromine has in its outer orbit? 5a) Helium‚ neon‚ and argon behave similarly in chemical reactions. What do you notice about the outer orbit of electrons in these elements? Hint: How many electrons did Bohr say each element could have in its outer shell? b) Krypton has the same chemical behaviour as helium‚ neon and argon. Where is Krypton found on the periodic table in relation to helium‚ neon and argon? c) Using your answer in 5a) as a guide‚ explain what

    Experiment 1 The Heat Capacity Ratio of Gases Purpose The purpose of this experiment is to calculate the heat capacity ratio of gases‚ Helium‚ Nitrogen and Carbon Dioxide‚ and compare with their theoretical values. Introduction Thermodynamics is the study of heat as it relates to energy and work. There are various properties which all relate to each other when determining the characteristic of a certain substance. One of such properties is heat capacity‚ which is the amount of heat energy

    exist. Combining a pair of helium atoms with 1s2 electron configurations would produce a molecule with a pair of electrons in both the bonding and the * antibonding molecular orbitals. The total energy of an He2 molecule would be essentially the same as the energy of a pair of isolated helium atoms‚ and there would be nothing to hold the helium atoms together to form a molecule. The fact that an He2 molecule is neither more nor less stable than a pair of isolated helium atoms illustrates an important

    EXPLORING LOIHI: THE NEXT HAWAIIAN ISLAND Twenty-one miles off the Big Island‚ nearly 3‚000 feet beneath the waves‚ an island is struggling to be born. Researchers are taking submersibles to the very bottom of the sea to watch the process unfold. Quiet as a falling pebble‚ the Pisces V submersible begins its descent to the ocean floor. Soon the downwelling light wanes and the pilot and a pair of scientists inside are swallowed up in inky blackness - a darkness as absolute as interstellar space

The Crust The outside of the earth is a thin crust which is approximately 20 to 40km thick. The crust is a formation of dips and hollows which are filled with water to form the oceans and seas. On top of the earth’s crust is an atmosphere
