Matter

Matter is the physical substance in the universe that has mass and occupies space. It is made up of atoms, which are the basic building blocks of matter. Atoms are made up of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus of the atom, while electrons orbit the nucleus.

The States of Matter

Matter can exist in three states: solid, liquid, and gas. Solids have a definite shape and volume. Liquids have a definite volume but no definite shape. Gases have no definite shape or volume.

The state of matter of a substance depends on its temperature and pressure. When the temperature of a substance is increased, it will change from a solid to a liquid to a gas. When the pressure of a substance is increased, it will change from a gas to a liquid to a solid.

The Properties of Matter

The properties of matter can be divided into two categories: physical properties and chemical properties. Physical properties are properties that can be observed without changing the chemical composition of the substance. Chemical properties are properties that describe how a substance reacts with other substances.

Some physical properties of matter include color, density, melting point, boiling point, and solubility. Some chemical properties of matter include flammability, reactivity, and toxicity.

The Importance of Matter

Matter is essential for life. All living things are made up of matter. Matter is also used to make the things we need to survive, such as food, clothing, and shelter.

The study of matter is called chemistry. Chemistry is a branch of science that deals with the composition, structure, properties, and reactions of matter.

Careers in Matter

There are many different careers that involve working with matter. Some of these careers include:

• Chemist
• Materials scientist
• Chemical engineer
• Pharmacist
• Toxicologist
• Physician
• Nurse
• Teacher
• Science writer

These careers require a strong understanding of matter and its properties.
