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

A lens is a transparent optical element with curved surfaces that refracts light, converging or diverging it. Click for previous year GE II 3. What is refraction? Refraction is the bending of light as it passes from one medium to another of different optical density. 4. Define reflection. Reflection is the bouncing back of light when it strikes the surface of an object. 5. What is the focal length of a lens? The focal length of a lens is the distan
