Which of the following substance is a gas at room temperature and atmospheric pressure

A substance is said to be a solid when its melting point lies below the room temperature at the normal pressure .

the degree of dissociation of PCI_(5) at a certain temperature and under one atmosphere pressure is 0.2. Calculate the pressure at which it is half dissociated at the same temperature.
