Answer 2

Answer:

• matter, material substance that constitutes the observable universe and, together with energy, forms the basis of all objective phenomena. ... The three most familiar forms, or states, of matter are solid, liquid, and gas. Heating and cooling a substance may change it from one state to another.
• molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical

properties of that substance

• In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
• Solvent, substance, ordinarily a liquid, in which other materials dissolve to form a solution. ... Their chief uses are as media for chemical syntheses, as industrial cleaners, in extractive processes, in pharmaceuticals, in inks, and in paints, varnishes, and lacquers.
• A physical reaction occurs when molecules undergo a molecular rearrangement to produce a physical change. The molecules are not chemically altered. ... A chemical reaction occurs when molecules are chemically altered as a result of interacting with one another, such as their bonds breaking.
• A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
