Distillation of Water by Solar Energy 1Anirudh Biswas* and 2Ruby RESEARCH ARTICLE RESEARCH ARTICLE ABSTRACT The purpose of this research is to design a water distillation system that can purify water from nearly any source‚ a system that is relatively cheap‚ portable‚ and depends only on renewable solar energy. From the results of project calculations a truthful estimate was made to prototype the most effective geometries of the distiller and trough concentration system‚ one that will maximize

Stewart Mrs.Ligammari Physics 11 9 June 2010 Is Pluto a Planet? When the International Astronomical Union announced that Pluto was no longer a planet people around the world were shocked. The 9 planets that they were used to knowing by the mnemonic code “My very elegant mother just served us nine pizzas” lost their pizza. Despite the fact that Pluto is a celestial object that orbits the sun‚ it cannot be considered a planet because of its inconsistency in orbit‚ its size‚ and the abundance

Light Affect Our Planet: Process Writing Thomas Tse October 31‚ 2012 Nowadays due to light pollution‚ it is hard to find a place in Hong Kong that can look at the stars clearly. It means that the light has disturbed our planet already; few types of animals can’t figure out that it’s morning or night. It affects the animal’s differentiation‚ communication and competition capacity. According to different problems‚ we must need to have some actions to help our society. There

The nature of sunspots Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They are caused by intense magnetic activity‚ which inhibits convection by an effect comparable to the eddy current brake‚ forming areas of reduced surface temperature. They usually appear as pairs‚ with each sunspot having the opposite magnetic pole to the other.[1] Although they are at temperatures of roughly 3000–4500 K (2700–4200 °C)‚ the

Atomic Structure Quiz Sample Questions 1. Why do only the number of protons and the number of neutrons make up the atomic mass of an element‚ but not the electrons? We generally do not use the number of electrons when calculating the atomic mass of an atom because they weigh so little (precisely 1/1836 AMU)‚ and only in precise calculations are the masses of the electrons included in atomic mass. 2. What was the difference between Mendeleev’s table and Mosley’s new arrangement? Mendeleev arranged
