What happens a solid dissolves?

Answer 1

To put it simply, the solid is pulled apart by the liquid into its simplest form - molecules or ions. These mix up with the particles of the solvent. For example, when dissolving sugar into water, the sugar crystals "break apart" one molecule at a time. We see this as the sugar crystals shrinking and then disappearing. In fact, they have not disappeared at all - they're just too small to see. In the case of an ionic compound, like salt, the ions are pulled apart by the liquid and float freely in the liquid. Since ions are charged particles, they allow the liquid to conduct electricity.

Answer 2

Complete dissolution would be each molecule of the solute (the thing dissolving) being surrounded by molecules of the solvent. The solid is still there, just broken apart into very small pieces that you can not see with your eyes. Some molecules themselves come apart to form ions in solution, such as salt. Others remain as whole molecules, like sugar.

Answer 3

During the melting process, the temperature remains constant even though heat is added at a constant rate. During this time, the heat is absorbed by the substance in the form of potential energy. Both solid and liquid phases of the substance are present during the melting process. As time goes on, the amount of liquid increases and the amount of solid decreases. In the liquid phase, particles are able to move past one another. The mobility prevents liquids from having a definite shape. However, they have a sufficient enough attractive force to give a liquid a definite volume. Basically, the bonds of a liquid becomes weaker than the bonds of a solid.
