Distillation involves boiling of a liquid until it turns to gas, leaving behind impurities which can not vapourise. The vapors will then be re condense to form the original liquid. The process of distillation illustrates the relationship between matter and energy because is show that matter changes state when enough energy is applied in the form of heat. When this heat is removed, then matter will return to its original state.
Plant Characteristics. Plants are autotrophs; they produce their own food. They do so via photosynthesis, which is the process of making nutrients such as sugars from light energy and carbon dioxide.

When atoms in a covalent bond share electrons unequally (one atoms pulls more than the other), the bond is said to be a polar bond is formed when electrons are unequally shared between two atoms. Polar covalent bonding occurs because one atom has a stronger affinity for electrons than the other (yet not enough to pull the electrons away completely and form an ion).
