View the full answer.Answer. Intermolecular forces serve to hold particles close together, whereas the particles' kinetic energy provides the energy required to overcome the attractive forces and thus increase the distance between particles. Changes in physical state may be induced by changing the temperature, hence, the average KE, of a given substance.Example 6.3.1: Sugar and Water. A solution is made by dissolving 1.00 g of sucrose ( C 12H 22O 11) in 100.0 g of liquid water. Identify the solvent and solute in the resulting solution. Solution. Either by mass or by moles, the obvious minor component is sucrose, so it is the solute. Water —the majority component—is the solvent.Intramolecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. Intermolecular forces are the attractions between molecules, which determine many of the physical properties of a substance. Figure 11.1.4 illustrates these different molecular forces.Capillary Action. Intermolecular forces also cause a phenomenon called capillary action, which is the tendency of a polar liquid to rise against gravity into a small-diameter tube (a capillary), as shown in Figure \(\PageIndex{3}\).When a glass capillary is is placed in liquid water, water rises up into the capillary.If the intermolecular forces are strong, then the melting point and boiling point will be high. If the intermolecular forces are weak, the melting and boiling point will be low. London forces vary widely in strength based on the number of electrons present.
