Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.

In this animated and interactive object, learners examine the properties of liquids, solids, and gases.

In this interactive object, students examine how the volume and temperature of an ideal gas relate under conditions of constant pressure and quantity.

Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.
