27 Μαρ 2021 · Explain on the basis of the kinetic theory of gases. Answer: On reducing the volume, the space for the given number of molecules of the gas decreases i.e. no. of molecules per unit volume increases.
Explain the concept of the kinetic theory of gases covered in Chapter 13 of NCERT Solutions for Class 11 Physics. The kinetic theory of gases is a theoretical model that describes the molecular composition of the gas in terms of a large number of submicroscopic particles, which include atoms and molecules.
2. Derive the Boyle's law using kinetic theory of gases? Ans: With the temperature constant, Boyle's law states that the volume of a given quantity of gas is inversely proportional to the pressure P, i.e. PV = constant. The pressure exerted by a gas is now given by the kinetic theory of gases. P Pressure V Volume V Average Velocity

Question 13. 1. Estimate the fraction of molecular volume to the actual volume occupied by oxygen gas at STP.’. Take the diameter of an oxygen molecule to be 3 A. Answer: Diameter of an oxygen molecule, d = 3 A = 3 x 10 -10 m. Consider one mole of oxygen gas at STP, which contain total NA = 6.023 x 10 23 molecules. Question 13. 2.
Chapter 13 Kinetic Theory . Answer The Following Question Answer. Question 1. Estimate the fraction of molecular volume to the actual volume occupied by oxygen gas at STP. Take the diameter of an oxygen molecule to be 3Å. Solution : Diameter of an oxygen molecule, d = 3Å Radius, r = d/2 = 3/2 = 1.5 Å = 1.5 × 10 –8 cm
