CBSE Class 11-science - Kinetic Theory of Gases Videos

• an ideal gas is enclosed in a cylinder at pressure 2 atm and temperature 300k the mean time between two successive collisions is 6×10–⁸s if the pressure is doubled and temperature is increased to 500k the mean time between two successive collisions will be close to
• Derive allotropic constant in terms of degree of freedom and hence find it's value for monotonic diatomic and polyatomic gases . 4. Derive the expression for mean free path for a gas .
• Kinetic and calculus method
• The graph shows the variation of PV with P of given masses of three gases A, B and C.  The temperature is kept constant.  Which of these is ideal graph?
• Is the r.m.s speed same as the average speed?
• When a gas is suddenly compressed, its temperature rises. Why?
• The volume of a gas sample is increased.  Why does the pressure, which is exerted by the gas, decrease?
• In terms of the kinetic theory of gases, explain why the pressure of a gas in a closed container increases when the gas is heated?
• 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.
• Calculate the root mean square velocity of oxygen molecules at 27^oC.  Take the density of oxygen to be 0.001424 g/cc.
