K is a CBSE 11 Chemistry 05.11 Kinetic Molecular Theory of Gases. 8527521718; Online Support; Menu. All the molecules of a particular gas are identical in mass and size and differ in these from gas to gas. Donate or volunteer today! In kinetic theory of gases, it is assumed that: (a) the collisions are not perfectly elastic. Sound travels from one point to another in the form of waves and vibrations.These waves are audible mechanical waves, which are known as sound waves.The particles of the medium in which these sound waves travel, oscillate forward and backwards in the direction of The molecules of a gas move haphazardly colliding among themselves and with the walls of the container and change their direction. NCERT Solutions for Class 11 Physics Chapter 13 Kinetic Theory 1. According to this theory, it is assumed that the reactant molecules are hard spheres and reaction Kinetic Theory Class 11 Notes Physics Chapter 13 The kinetic theory was developed in the nineteenth century by Maxwell, Boltzman and others. Correctly explains specific heat capacities of many gases. 1)Every gas is made up of a large number of extremely small particles called molecules. Kinetic molecular theory of gases. Kinetic Theory. We shall learn all about the kinetic theory of gases in this chapter. Total Kinetic energy is conserved. If three molecules have velocities 0.5, 1 and 2 km/s respectively, calculate the ratio of the root mean square speed and average speed. N A = 6.023 X 10 23 per gram mole (ii) At STP or NTP (T = 273 K and p = 1 atm 22.4 L of each gas has 6.023 x 10 23 molecules. Question 25. This is possible as the inter-atomic forces, which are short range forces that are important for solids and liquids, can be neglected for gases.
