1.	When a compressed real gas is made to expand adiabatically through a porous plug, how does the temperature change ?
Answer» Solution :When a compressed real gas is allowed to expand adiabatically through a porous PLUG to a region of low against the molecules attractive forces, so work is DONE by the gas molecules at the expense of INTERNAL energy of the gas. THEREFORE, COOLING occurs as the gas expands.
