Coal gas contains 5-9% (v/v) ethylene.

IF the volume of a container is V, the pressure on the walls of the container by a gas is p and internal energy of the gas is U, then

If pressure of real gas CO_2 in a container is given by P=(RT)/(2V-b)- a/(4b^2) , then the mass of the gas in the container is

Consider an ideal gas confined in an isolated closed chamber. As the gas undergoes an adiabatic expansion the average time of collision between molecules increases as V^q where V is the volume of the gas. The value of q is (gamma=C_p/C_v)

At constant temperature and pressure, the compressbility factor (Z) for one mole of a van der waals gas is 0.5. if the volumes of the gas molecules are considered to negligible, then show that a=(1)/(2)V_(m)RT , where V_(m) and T are the molar volume and temperature of the gas respectively.
