Polymer is a substance made up of a large number of smaller molecules that link together to form larger molecules. The particles in liquids are arranged in a random way, and are close together, touching many of their neighbours. Collections of pieces, such as the particles of a powder, may have properties that the individual pieces do not have. If the temperature increases, the pressure of the gas increases. This can also be explained by the fact that water molecules are very attracted to each other. RUMPUS! Molecules in a sample are vaporized (converted to the gas phase by heating).
