List of top Physics Questions on The Kinetic Theory of Gases asked in WBJEE

2 moles of an ideal gas with \( \frac{C_p}{C_v} = \frac{5}{3} \) are mixed with 3 moles of another ideal gas with \( \frac{C_p}{C_v} = \frac{4}{3} \). The value of \( \frac{C_p}{C_v} \) for the mixture is

For an ideal gas, a cyclic process ABCA as shown in the P–T diagram. When represented in P–V plot, it would be 

Let \( \bar{v}, v_{rms}, v_p \) denote the mean speed, root mean square speed and most probable speed of molecules of mass \( m \) in an ideal monoatomic gas at temperature \( T \). Which statements are correct?
Let \( \bar{V} \), \( V_{\text{rms}} \), \( V_p \) denote the mean speed, root mean square speed, and most probable speed of the molecules of mass \( m \) in an ideal monoatomic gas at absolute temperature \( T \) Kelvin. Which statement(s) is/are correct?
The speed distribution for a sample of \(N\) gas particles is shown below. \(P(v) = 0\) for \(v > 2v_0\). How many particles have speeds between \(1.2v_0\) and \(1.8v_0\)?
