This Quiz Is About The Three States Of Matter

The three states of matter are solid, liquid, and gas. Gas is the correct answer because it is the third state of matter, characterized by particles that are widely spaced and move freely. Unlike solids and liquids, gases do not have a fixed shape or volume and can expand to fill the container they are in. Examples of gases include oxygen, nitrogen, and carbon dioxide.

When a nail rusts, it undergoes a chemical change. This is because rusting is a chemical reaction that occurs when iron reacts with oxygen in the presence of water or moisture. During this process, the iron atoms combine with oxygen atoms to form iron oxide, which is the rust that we see on the surface of the nail. This change in the composition and properties of the nail is a clear indication of a chemical change taking place.

A chemical change refers to a process in which the composition of a substance is altered, resulting in the formation of a new substance. This can involve the breaking and forming of chemical bonds, resulting in a different arrangement of atoms. Therefore, the statement that a chemical change is when a new substance is formed is true.

A chemical change refers to a process in which one or more substances are transformed into entirely new substances with different properties. This can involve the formation of new chemical bonds, the rearrangement of atoms, or the breaking of existing bonds. It is different from a physical change, such as a change in shape or state, where the original substance remains the same. Therefore, the correct answer is "anything that creates a new substance."

The correct answer is "anything that takes up space." This definition of matter is based on the concept that matter occupies space and has a physical presence. It includes everything that has mass and occupies a certain volume. This definition encompasses all forms of matter, whether they are visible or not, and emphasizes the fundamental characteristic of matter, which is its ability to occupy space.

Evaporation is a physical change, not a chemical change. It is the process by which a liquid changes into a gas due to the absorption of heat energy. During evaporation, the molecules of the liquid gain enough energy to overcome the forces of attraction between them and escape into the air as vapor. No new substances are formed, and the chemical composition of the liquid remains the same. Therefore, evaporation does not involve any chemical reactions and is considered a physical change.

Plasma is actually not the most common state of matter on Earth. The most common state of matter on Earth is solid, followed by liquid and then gas. Plasma, which consists of charged particles, is relatively rare on Earth and is typically found in extreme conditions such as lightning, stars, and certain laboratory experiments. Therefore, the statement that plasma is the most common state of matter on Earth is false.

The given answer includes examples of chemical changes because they involve the formation of new substances with different chemical properties. Wood burning involves the combustion of wood, which produces ash and smoke. Metal rusting is the result of a chemical reaction between metal and oxygen, forming metal oxide. Salt dissolving in water involves the separation of sodium and chloride ions from the salt crystal. Food digesting involves the breakdown of complex molecules into simpler ones through chemical reactions in the digestive system. Fireworks exploding involve the combustion of various chemicals, resulting in the release of light, heat, and gas.
