In which gas - `H_(2)` or `O_(2)` will sound travel with greater speed under given conditions of temperature and pressure?

At a given volume and temperature, the pressure of a gas:

Calculate the ratio of the mean free paths of the molecules of two gases having molecular diameters 1 and 2. The gases may be considered under identical conditions of temperature, pressure and volume.

A gaseous mixture of propane and butane of volume 3 litre on complete combustion produces 11.0 litre CO_2 under standard conditions of temperature and pressure. The ratio of volume of butane to propane is :

When sound travels through gases,is it under isothrmal condition or adiabatic conditions?And why?

A gas can be very easily liquefied at low temperature and under low pressure. (True/False)

In which of the following reactions, H_(2)O_(2) is acting as a reducing agent?

If c is r.m.s. speed of molecules in a gas and v is the speed of sound wave in the gas , show that c/v is constant and independent of temperature for all diatomic gases.
