Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314

1. INTRODUCTION The sun is the largest source of renewable energy and this energy is abundantly available in all parts of the earth. It is in fact one of the best alternatives to the non-renewable sources of energy. Solar energy has been used since prehistoric times‚ but in a most primitive manner. Before 1970‚ some research and development was carried out in a few countries to exploit solar energy more efficiently‚ but most of this work remained mainly academic . After the dramatic rise in oil

Chemistry assignment Introduction: Throughout modern day society metals are constantly used‚ in fact mankind has been heavily dependent on metals for the last several hundred years. But the science behind metals has only been discovered in recent years and has now become known to people that we simply could not live without them. Metals make up around 80% of the elements (currently discovered). They are used in everyday items that society depends on‚ such as: cars‚ re-bars for building‚ window

DAMS: GOOD OR BAD Introduction The unequal availability of resources leads to the development of methods to store them. Water as the prime resource for survival has been the determining factor for human settlements‚ been the sole reason for communities to thrive and for long formed the basis for wars. In locations where the appearance of rainfall is scanty and unreliable‚ the need to store water has given rise to the creation of ‘tankas’‚ creation of man-made lakes and similar reservoirs
