In a cubical box of volume V, there are N molecules of a gas moving randomly. If m is mss of ech molecule and`V^(2)` is the meansquare of x component of the velocity of molecules, then the pressure of the gas is-

Number of molecules in V litre of a gas at NTP is

At temperature T ,N molecules of gas A each having mass m and at the same temperature 2N molecules of gas B each having mass 2m are filed in a container.The mean square velocity of molecules of gas B is v^(2) and mean square of x component of velocity of molecules of gas A is w^(2) .The ratio of w^(2)/v^(2) is :

There are N molecules of a gas in a box. If the number of molecules is increased to 2 N, what will be the effect on the root mean square speed of molecules.

If the rms velocity of the molecules of a gas in a container be doubled then the pressure of the gas will.

2N molecules of an ideal gas X, each of mass m, and 4N molecules of another ideal gas, Y, each of mass 3m are maintained at the same absolute temperature in the same vessel. The root mean square speed of molecules of X type is v and the root mean square of the component of velocity of molecules of gas Y, along the X axis is u, then v : u ​ is
