Properties of Matter

Front

Physical Property Noun

---

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

Back

Physical Property

---

A characteristic of matter that can be observed or measured without changing the substance's fundamental identity.

---

Example: Different physical properties like density and solubility are shown with examples.

Front

Chemical Property Noun

---

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

Back

Chemical Property

---

A characteristic of matter that describes its ability to undergo changes that transform it into different substances.

---

Example: This image shows how methane and oxygen react to form carbon dioxide and water, demonstrating a chemical property.

Front

Qualitative Property Noun

---

[kwol-i-tey-tiv prop-er-tee]

Back

Qualitative Property

---

A characteristic of matter that is described with words and observed using the senses, like color or odor.

---

Example: Gold's shiny, yellow color is a qualitative property observed with senses.

Front

Quantitative Property Noun

---

[kwon-ti-tey-tiv prop-er-tee]

Back

Quantitative Property

---

A characteristic of matter that can be measured and expressed using numbers, such as length or temperature.

---

Example: A thermometer measures temperature, showing how quantitative properties are expressed with numbers.

Front

Mass Noun

---

[mas]

Back

Mass

---

The measure of the amount of matter contained within a physical body or substance, independent of gravity.

---

Example: A balance scale shows a feather and a rock, illustrating mass by comparing their matter amounts.

Front

Weight Noun

---

[weyt]

Back

Weight

---

The measure of the force of gravity acting on an object's mass, which can vary with location.

---

Example: A balance scale shows how gravity affects the weight of a feather and a rock differently.

Front

Volume Noun

---

[vol-yoom]

Back

Volume

---

The amount of three-dimensional space that a substance or object occupies, measured in units like mL or cm³.

---

Example: The image shows objects in beakers with water, demonstrating how volume is measured in milliliters.

Front

Density Noun

---

[den-si-tee]

Back

Density

---

The measurement of how much mass is contained in a given unit of volume for a substance.

---

Example: Objects with different densities float or sink in water, showing how mass and volume relate.

Front

Size-dependent property Noun

---

[sahyz-di-pen-dent prop-er-tee]

Back

Size-dependent property

---

A physical property that changes when the size or amount of the substance changes, such as mass or volume.

---

Example: The diagram lists mass, weight, and volume as size-dependent properties, but lacks detailed explanation.

Front

Size-independent property Noun

---

[sahyz-in-di-pen-dent prop-er-tee]

Back

Size-independent property

---

A physical property that remains the same regardless of the amount or size of the substance, like density.

---

Example: The flowchart shows that density is a size-independent property, as it does not change with the amount of substance.
