Notes On Gaseous State This page provides you all details about the gaseous state of BSc standard. Concerned problems will be solved at the end of each concept. Continue till the end to find the easiest explanation of every concept you need in this regard . Postulates of Kinetic Theory of Gases: 1. All gas consist of a very large number of minute particles, called molecules. 2. The gas molecules are extremely small in size and are separated by large distance. The actual volume of the gas molecules is thus negligible as compared to the total volume occupied by the gas. 3. The pressure exerted by the gas is due to the bombardment of the molecules on the walls of the vessel. 4. The gas molecules collide with one another and also with the walls of the vessels. These collisions are perfectly elastic and there is no loss of energy during these collisions. 5. The distance between the gas molecules are very large. Thus, there is no effective force of attraction or r
Chemicals in fruits, Health Issues and how to get rid of them. As we all know fruits are one of most important part of the human diet, fresh, testy and healthy fruits attract special attention. Human in general give importance to the colour of the fruits in the market (if color looks good then the fruits are OK). Many of us are not aware of the chemicals used for colouring and adding test to fruits. Some of them have less effect tot human health while some others have severe health consequences. This post elaborates chemicals of these kind and suggests possible methods to get rid of these chemicals. For your clarification, no fruits are left chemically untouched, hence at least wash fruits several times before you eat. Chemicals used to ripen banana: The acetylene gas produced from hydrolysis of calcium carbide is used next to ethylene to ripen bananas. This calcium carbide is not safe as it may contain traces of arsenic and phosphorus hydride like much
