Two monoatomic ideal gases 1 and 2 of molecular masses m^(1) and m​^(2) respectively are enclosed in separate containers kept at the same temperature. The ratio of the speed of sound in gas 1 to that in gas 2 is given by :-

Two monatomic ideal gases 1 and 2 of molecular masses m_(1) and m_(2) repectively are enclosed in separate containers kept at the same temprature. The ratio of the of sound in gas 1 to that in gas 2 is given by

Two non-reactive monoatomic ideal gases have their atomic masses in the ratio 2:3. The ratio of their partial pressures, when enclosed in a vessel kept at a constant temperature, is 4:3. The ratio of their densities is

Two non-reactive monoatomic ideal gases have their atomic masses in the ratio (2 : 3) . The ratio of their partial pressure, when enclosed in a vessel kept at a constant temperature, is (4 : 3) . The ratio of their densities is :

Two separate bulbs contain ideal gas A and B . The density of a gas A is twice that of a gas B . The molecular mass of A is half that of gas B . The two gases are at the same temperature. The ratio of the pressure of A to that gas B is

The velocity of sound in an ideal gas at temperature T_1 and T_2 K are v_1 and v_2 respectively. If the root mean square velocity of the same gas at same temperature are c_1 and c_2 then-
