Matter Noun

---

[mat-er]

Back

Matter

---

Anything that has mass and takes up space, existing in various forms such as solid, liquid, or gas.

---

Example: The image shows matter in solid, liquid, and gas forms with particle arrangements and temperature scale.

Chemistry Noun

---

[kem-iss-tree]

Back

Chemistry

---

The scientific study of the properties and behavior of matter, including its composition, structure, and changes.

---

Example: This image shows basic lab equipment used to study the properties of matter in chemistry.

Substance Noun

---

[sub-stans]

Back

Substance

---

A single kind of matter that is pure and has a specific, definite makeup or chemical composition.

---

Example: Pure substances like bromine and water have a definite chemical composition and cannot be separated by physical means.

Physical Property Noun

---

[fiz-i-kuhl prop-er-tee]

Back

Physical Property

---

A characteristic of a substance that can be observed or measured without changing its chemical identity.

---

Example: The image lists physical properties like mass and conductivity, showing they can be observed without changing the substance.

Solubility Noun

---

[sol-yoo-bil-i-tee]

Back

Solubility

---

A physical property describing the ability of a substance to dissolve in a solvent to form a solution.

---

Example: Solubility is shown by how a solute dissolves in a solvent to form a solution, with different saturation levels.

Chemical Property Noun

---

[kem-i-kuhl prop-er-tee]

Back

Chemical Property

---

A characteristic of a substance that describes its ability to undergo a chemical change and form new substances.

---

Example: Methane burns in oxygen to form carbon dioxide and water, showing a chemical property.

Front

Flammability Noun

---

[flam-uh-bil-i-tee]

Back

Flammability

---

A chemical property describing how easily a substance can burn or ignite, causing fire or combustion.

---

Example: Burning wood shows how easily it can catch fire, demonstrating flammability.

Atom Noun

---

[at-uhm]

Back

Atom

---

The basic and smallest particle of a chemical element from which all matter is made.

---

Example: The image shows an atom with protons, neutrons, and electrons, explaining its basic structure.

Front

Element Noun

---

[el-uh-muhnt]

Back

Element

---

A pure substance consisting of only one type of atom, which cannot be broken down into simpler substances.

---

Example: A helium atom with protons, neutrons, and electrons shows an element as a pure substance.

Front

Chemical Bond Noun

---

[kem-i-kuhl bond]

Back

Chemical Bond

---

A lasting force of attraction that holds two or more atoms together to form molecules or compounds.

---

Example: The image shows hydrogen bonds as dotted lines between water molecules, illustrating how chemical bonds hold atoms together.
