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
Thermodynamics Short questions and Answers. 1. Thermodynamics is the branch of physics that deals with the study of energy and its transformations in systems. 2. It encompasses the principles governing heat, work, temperature, and energy transfer. 3. The laws of thermodynamics provide a framework for understanding the behavior of macroscopic systems. Get Notes on Thermodynamics for BSc here. 4. The first law of thermodynamics states that energy is conserved in a closed system. 5. It relates the change in internal energy of a system to the heat added to it and the work done on or by the system. 6. The second law of thermodynamics establishes the concept of entropy, which characterizes the direction of spontaneous processes. 7. It states that the entropy of an isolated system tends to increase over time. 8. The third law of thermodynamics states that the entropy of a perfect crystal approaches zero as its temperature approaches absolute zero. 9. The c
