An HCl molecule has rotational, translational and vibrational motions. If the rms velocity of HCl molecules in its gaseous phase is vec(v), m is its mass and k_(s) is Bolzmann constant, then its temperature will be (mv^(2))/(nk_(B)) , where n is __________ .
The r.m.s. speed of the molecules of a gas at 100^(@)C is v. The temperature at which the r.m.s. speed will be sqrt(3)v is
Consider a mixture of gas molecule of types A, B and C having masses m_(A) lt m_(B) lt m_(C) . The ratio of their root mean square speeds at normal temperature and pressure is :
The ratio of V_rms of O_2 and V_MP of SO_2 at room temperature will be
The root mean square speed fo molecules of nitrogen gas is v at a certain temperature. When the temperature is doubled, the molecules dissociate into individual atoms. The new rms speed of the atom is:
The r.m.s. speed of the molecules of an enclosed gas in C_(rms) . If pressure is made four times keeping the temperature constant, the r.m.s. speed will be
The velocity of molecules of a gas at temperature 120 K is v. At what temperature will the velocity be 2v?
The mass of an oxygen molecule is about 16 times that of a hydrogen molecule. At room temperature the 'rms' speed of oxygen molecules is v. The 'rms' speed of oxygen molecules is v. the 'rms' speed of the hydrogen molecules at the same temperature will be
Molar mass of certain gas A is half that of B. If rms speed of molecules of A at certain temperature is 200 ms^(-1) . The rms speed of B at the temperature half that of A will be
