Editing Law of corresponding states

The '''law of corresponding states''' is an empirical law encapsulates the finding that the equations of state for many real gases are remarkably similar when they are expressed in terms of reduced [[temperature]]s (<math>T_r = T/T_c</math>), [[pressure]]s,  (<math>p_r = p/p_c</math>) and volumes (<math>V_r = V/V_c</math>).
