Kinetic Theory of Gases MCQs for NEET — Physics Questions with Answers

The temperature at which real gases obeys the ideal gas laws over a wide range of pressure in called

A bottle of $NH_3$ and a square of dry HCL connected through a long tube are opened simultanuulely at both ends, the white ammonia chloride ring first fromed willbe (IIT- 1988)

At $ 100 ^\circ C $ and 1 atm, if the density of liquid water is $ 1.0 g ^{-3} $ an and that of water vapour is $ 0.006g cm^{-3} $ , then the volume of water moleules in 1 L of steam at this temperature is (IIT- 2000)

Two separate bulbs contains gas A and gas B the density of A is twice as that of gas B. The molecular. mass of gas A is half as that of B If two gases are at same temp, the ratio of the pressure of A to that of B is

50 ml of a gas A diffuse through a membrane in the same time as for this diffiusion of 40 mlof a gas B under identical pressure temperature conditions . If the molecular weight of A = 64, that of B would be (CBSC - 1992)

Which of the following statement is false ? (BHD - 1994)

Density ratio of $ O_2 and H_2 $ gas is 16 : 1 The ratio of their rms velocities will be

At constant temperature and pressure, the rate of diffusion $ D_A and D_B $ of gases A and B having densities $P_A and P_B $ are related by the expressions (IIt Screening - 1993)

If 300ml of gas at $ 27 ^\circ C is cooled to 7 ^\circ C $ at constant pressure Its final volume will be (AIIMS - 2000)

Positive deviation from ideal gas behaviour takes place. because of
