What is matter?

Matter is any substance that has mass and occupies space. It is made up of particles such as atoms and molecules that interact with each other through various forces to form different types of substances. Matter can exist in different states, including solid, liquid, and gas, and possesses properties such as density, volume, and temperature.

Give an example of a solid matter.

An example of a solid matter is a rock.

Give an example of a liquid matter.

Water is an example of a liquid matter.

Give an example of a gas matter.

An example of a gas matter is oxygen.

What are the three states of matter?

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

How is matter different from energy?

Matter is composed of particles that have mass and occupy space, while energy does not have mass and does not occupy space. Matter can exist in various forms such as solid, liquid, or gas, and can be physically measured and observed. On the other hand, energy is the ability to do work or produce heat, and it exists in various forms like kinetic, potential, thermal, electromagnetic, and nuclear. Both matter and energy are fundamental components of the universe, and they can be converted into each other through processes like nuclear reactions or changes in state.

Can matter be created or destroyed?

According to the law of conservation of mass, matter cannot be created or destroyed, but it can only change forms. This means that the total amount of matter in a closed system remains constant, even though it may undergo various transformations or changes in state.

What is the difference between a physical and chemical change in matter?

A physical change involves a change in the form or state of matter without altering its chemical composition, such as melting, freezing, or evaporating. In contrast, a chemical change results in the formation of new substances with different chemical compositions, such as rusting, burning, or cooking. The key distinction is that physical changes are reversible through processes like melting or freezing, while chemical changes are usually irreversible and involve the formation of new chemical bonds.

Give an example of a physical change in matter.

Melting an ice cube is an example of a physical change in matter. When heat is applied to the solid ice cube, it changes its state from a solid to a liquid, without altering its chemical composition.

Give an example of a chemical change in matter.

An example of a chemical change in matter is the rusting of iron. When iron comes into contact with oxygen and water, it undergoes a chemical reaction that forms iron oxide, or rust. This change is irreversible and alters the chemical composition of the iron, showing characteristics different from the original material.
