A crystal and its melt readily conduct electricity. The crystal also has a luster and is easily deformed. Liquid Q is a polar solvent and liquid R is a nonpolar solvent. A liquid is in equilibrium with its vapor. Some H 2 O at -50 C is heated to 120 o C at a constant pressure of 0.5 atm.
All sides are equal in length and all angles are right angles.
There is an atom at each corner and one in the absolute center. All sides are equal in length and all angles are right angles. There is an atom at each corner and one at the center of each side. A crystal does not conduct electricity, yet its melt and aqueous solutions do. It is hard and brittle and melts at a high temperature.
