What is the definition of matter?

Matter is anything that has mass and occupies space, thus encompassing all substances that compose the physical universe, including elements, compounds, and mixtures. It is the material substance making up physical objects that can be observed and measured through its properties such as mass, volume, and density.

How can matter change from one state to another?

Matter can change from one state to another through the processes of melting, freezing, evaporation, condensation, sublimation, and deposition. These changes occur when the temperature or pressure of the substance is altered, causing the arrangement of the particles to change. For example, when a solid is heated, it may melt into a liquid, and when a liquid is cooled, it may freeze into a solid. Similarly, a liquid can evaporate into a gas, and a gas can condense back into a liquid. Sublimation occurs when a solid turns directly into a gas, and deposition is when a gas changes directly into a solid.

What is physical change?

Physical change refers to a change in a substance that does not alter its chemical composition. This means the substance may change its shape, size, state of matter, or other physical properties without changing the basic identity of the material. Examples of physical changes include melting, freezing, dissolving, or changing the state of matter from solid to liquid or gas.

Give an example of a physical change.

An example of a physical change is melting ice into water. In this process, the ice changes from a solid state to a liquid state without any change in its chemical composition.

What is chemical change?

A chemical change is a process in which one or more substances are transformed into one or more new substances with different chemical properties. This change involves the breaking and forming of chemical bonds, resulting in the creation of new molecules or compounds that are distinct from the original substances. Examples of chemical changes include burning, rusting, and digestion.

Provide an example of a chemical change.

An example of a chemical change is the reaction between iron and oxygen to form rust. When iron reacts with oxygen in the presence of water, it undergoes a chemical transformation where iron atoms combine with oxygen atoms to create iron oxide, resulting in the formation of rust. This change is irreversible and involves the formation of new chemical compounds with different properties from the original substances.

What are the three states of matter?

The three states of matter are solid, liquid, and gas.

What is evaporation?

Evaporation is the process in which liquid water turns into water vapor by gaining heat energy from its surroundings and breaking free from the surface of the liquid. This natural phenomenon occurs in bodies of water, such as oceans, lakes, and rivers, as well as on moist surfaces like wet soil or wet clothing, due to the kinetic energy of water molecules at the surface.

How does melting differ from evaporation?

Melting is the process where a solid substance turns into a liquid state as a result of gaining heat energy. On the other hand, evaporation is when a liquid substance turns into a gas state due to the input of heat energy. While melting involves the change in state from solid to liquid, evaporation involves the change in state from liquid to gas.

What happens during a combustion reaction?

During a combustion reaction, a fuel (such as a hydrocarbon) combines rapidly with oxygen gas in the presence of heat to produce carbon dioxide and water, along with release of energy in the form of heat and light. This process is exothermic, meaning it releases energy, and is a key aspect of how fuels are used to generate heat and power in various applications, such as in engines and power plants.
