Chemical properties of the sun. The total energy emission of the sun or luminosity is 4 10 26 watts. This is found by measurement of the solar constant the energy received per square meter 1360 wattsm 2 by a surface perpendicular to the direction of the Sun at a distance of 1 astronomical unit and multiplying by the surface area of a sphere of radius 1 AU. The Sun is classified as a G2 V star with G2 standing for the second hottest stars of the yellow G classof surface temperature about 5800 kelvins Kand the V representing a main sequence or dwarf star the typical star for this temperature class.
G stars are so called because of the prominence of a band of atomic and molecular spectral. The Sun contains about 92 hydrogen and 8 helium with just a tiny bit of the other common elements we find on Earth. Compare that to Earth where the most common elements are oxygen magnesium silicon and iron.
On Earth hydrogen barely makes the top 10 list of common elements and helium is extremely rare. You may know the Sun consists mainly of hydrogen and helium. Have you ever wondered what about the other elements in the Sun.
About 67 chemical elements have been detected in the sun. Im sure youre not surprised that hydrogen is the most abundant element accounting for over 90 of the atoms and over 70 of solar mass. About 73 of the Suns mass is hydrogen and another 25 is helium.
All the other chemical elements including those we know and love in our own bodies such as carbon oxygen and nitrogen make up only 2 of our star. The 10 most abundant gases in the Suns visible surface layer are listed in Table 1. The Sun is the star at the center of the Solar SystemIt is a nearly perfect sphere of hot plasma heated to incandescence by nuclear fusion reactions in its core radiating the energy mainly as visible light and infrared radiation.
It is by far the most important source of energy for life on EarthIts diameter is about 139 million kilometres 864000 miles or 109 times that of Earth. Properties of the sun 1. Introduction to Stars A.

The solar chemical composition is an important ingredient in our understanding of the formation structure and evolution of both the Sun and our Solar System. Furthermore it is an essential reference standard against which the elemental contents of other astronomical objects are compared.
Sunflower oil is the non-volatile oil pressed from the seeds of sunflower. Sunflower oil is commonly used in food as a frying oil and in cosmetic formulations as an emollient. Sunflower oil is primarily composed of linoleic acid a polyunsaturated fat and oleic acid a monounsaturated fat.
Through selective breeding and manufacturing processes oils of differing proportions of the fatty acids are produced. One of the chemical properties of plastics is the absorption of UV light especially from sunlight. Cracking when subjected to heat and stress is the other chemical property of the plastics.
Composition of Earths crust. The table of elements at left was constructed from analysis of the solar spectrum which comes from the photosphere and chromosphere of the Sun. Physical sunscreens such as zinc oxide and titanium dioxide work by reflecting the photons of light up and away from the skin so there is no absorption of energy.
Hence also there is no chemical reaction. The creation of free radicals is thus minimized. During transportation the base product has to be kept at a consistent temperature because of its viscous properties.
Whereas the temperature in Sun Chemicals previous tanks was controlled by a generator the design improvements in the new tanks includes extra insulation which delivers an increased insulation value of 15 compared with the initial eight tanks as well as a self-heating system.
