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
Most important 100 points on periodic table Find here most important 100 short questions on periodic table: 1. The periodic table is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties. 2. It was first proposed by Russian chemist Dmitri Mendeleev in 1869. 3. The modern periodic table consists of 118 elements, including 94 naturally occurring elements and 24 synthetic elements. 4. Elements are arranged in order of increasing atomic number from left to right and top to bottom. 5. Each element is represented by its chemical symbol, which is derived from its name. 6. Elements in the same vertical column are called groups or families and have similar chemical properties. 7. The periodic table is divided into several blocks: s-block, p-block, d-block, and f-block. 8. The s-block consists of groups 1 and 2, including hydrogen and h
