Sugar dissolving in water is a physical change and not a chemical one. Chemical changes only occur when new substances form. Dissolving sugar in water does not cause a chemical reaction to take place. More »

Water temperature affects the rate at which sugar dissolves. Sugar dissolves faster in warmer water than it does in cooler water. Two things are required for a substance to dissolve and create a solution: the substance i... More »

Alterations to the electron-based ionic or covalent bonds between ions or atoms happen during a chemical change. Such changes result in one or more new substances with different physical and chemical properties. This typ... More »

Sugar water freezes faster than salt water, because salt has more molecules than sugar. Normally, water freezes at 32°F, however, when a substance is added to the water, it lowers its freezing point. This is not because ... More »

Sugar dissolves in water because both substances are polar substances. Water dissolves the majority of substances that are polar or ionic. The fact that sugar dissolves in water is unusual because most molecular compound... More » Science Chemistry Solutions & Mixtures

Sugar water is an example of a solid-liquid solution. Sugar, a solid, is the solute; water, a liquid, is the solvent. Dissolving the solid in the liquid creates the solution. More »

Matter changes via two processes: a physical change or a chemical change. Physical changes retain the fundamental identity of a substance without modifying its composition, while chemical changes alter matter into anothe... More »
