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
Chemical Innovations: Contributions from Pakistan and Bangladesh Both Pakistan and Bangladesh have made commendable contributions to the field of chemistry despite various challenges. In Pakistan, luminaries like Abdus Salam, although renowned for his work in theoretical physics, began his academic journey with a background in chemistry. https://creativecommons.org/publicdomain/zero/1.0/ The country's research institutions, including the Pakistan Council of Scientific and Industrial Research (PCSIR) and leading universities, have consistently engaged in groundbreaking chemical research encompassing fertilizers, pharmaceuticals, and petrochemicals. Similarly, Bangladesh has seen notable advancements in the realm of chemistry, with figures like Dr. Mohammad Ataul Karim making significant strides in chemical engineering and thermodynamics. The country's robust pharmaceutical industry and research institutions, such as the Bangladesh Council of Scientific and Industrial Research
