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
Generic Elective Chemistry- Paper I
Students of different honours often find it difficult to get G.E (Generic elective) chemistry question papers and solution. This post will help you meet all your needs by bringing you the most probable questions (Long and Short) in GE -I chemistry. Read to the end carefully and find important links.
The GE - I (Chemistry) consists of two parts : Inorganic and Organic. Several most probable question have been prepared from both of these sections. Prepare all the long questions and automatically you will be able to answer the short questions. Most probable short questions are given is another link below.
Now a days, direct chemistry questions are not asked rather asked from bit by bit. Hence you have to read and memorize the concept clearly. If you want to get GE - I chemistry full course lecture, then download our App from Play Store by searching Soul of Chemistry. Click here to get our App. previous
