Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of the gas is reduced. The particles in a gas are further apart than

Water is an integral part of land/soil productivity. Its misuse can cause both degradation and erosion of soils. Management of water resource is considered to necessary for well being of human life as well as crop yields. There is a gap between the seasonal availability of water and its equitable supply throughout the year. Accordingly the storage of water and passage through soils is very important. It is well known that about 70% area in this country is subject to varying degree of water stress

Chemical reactions are the basis of life on earth. As human beings‚ we are little more than the naturally abundant elements of which we are composed and the reactions between the compounds that they form. After all‚ how could life exist without water? Oxygen transport in a body the size of the human body would be impossible without the aid of a complex like hemoglobin. Besides being the basis of many of life’s intangibles‚ chemistry also plays an active role in our daily lives. Take for instance

Oil Spills and Its Effects on Marine Life Many people do not realize the impact of the oil spills that occur in the ocean. It is like putting water into a heated oil frying substance. It is quite catastrophic. With all the oil spills that have already occurred it is important to help clean ‚and prevent oil spills from reoccuring. There is indeed a lot of reasons as to why we should clean and help prevent oil spills from happening but here are the three main reasons. First reason being oil spills
