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
Ten Notable Inventions in Chemistry Arising from Laboratory Accidents In the world of scientific research, some of the most remarkable discoveries and groundbreaking inventions have emerged by happenstance. Serendipity often strikes in the form of laboratory mishaps or catastrophe, where scientists stumble upon novel phenomena or unintended outcomes that reshape our understanding of chemistry. These fortunate mishaps have catalyzed technological advancements, sparked new directions, unlocked hidden potentials, and revolutionized industries. In this article, we explore ten notable inventions in chemistry that owe their existence to laboratory accidents, showcasing the power of unintended discoveries and the beauty of scientific serendipity. 1.Vulcanized Rubber (1839): Charles Goodyear accidentally dropped a mixture of rubber and sulfur on a hot stove, resulting in the formation of a durable and elastic material known as vulcanized rubber. This discovery revolutionized the rubber in
