---

Example: A digital thermometer with a probe displays temperature, showing how it measures heat.

Front

Temperature Noun

---

[tem-per-uh-cher]

Back

Temperature

---

A physical quantity that expresses the degree of hotness or coldness of a substance or object.

---

Example: Molecules in hot areas move faster, showing higher temperature compared to cooler areas.

Front

Density Noun

---

[den-si-tee]

Back

Density

---

The measure of mass per unit of volume, indicating how tightly packed the matter in a substance is.

---

Example: Objects with different densities float or sink in water, showing how tightly packed their matter is.

Front

Buoyancy Noun

---

[boi-uhn-see]

Back

Buoyancy

---

The upward force exerted by a fluid that opposes the weight of an immersed object, causing it to float.

---

Example: The image shows how different objects float or sink in water, demonstrating buoyancy.

Front

Fahrenheit Noun

---

[far-en-hahyt]

Back

Fahrenheit

---

A temperature scale where the freezing point of water is 32 degrees and the boiling point is 212 degrees.

---

Example: The image shows Fahrenheit and Celsius scales, highlighting water's freezing and boiling points.

Front

Celsius Noun

---

[sel-see-uhs]

Back

Celsius

---

A temperature scale where the freezing point of water is 0 degrees and the boiling point is 100 degrees.

---

Example: The image shows water freezing at 0°C and boiling at 100°C, illustrating the Celsius temperature scale.

Front

Centigrade Noun

---

[sen-ti-greyd]

Back

Centigrade

---

The former name for the Celsius temperature scale, based on a 100-degree interval between freezing and boiling points.

---

Example: A thermometer showing the centigrade scale, illustrating the Celsius temperature range.

Front

Expands Verb

---

[ik-spandz]

Back

Expands

---

To increase in size, number, or volume, often as a result of being heated.

Example: Heating the metal ball causes it to expand and not fit through the ring.

Front

Contracts Verb

---

[kon-trakts]

Back

Contracts

---

To decrease in size, number, or volume, often as a result of being cooled.

---

Example: Cooling causes particles to move slower and closer, showing contraction.

Front

Bimetallic Strip Noun

---

[bahy-muh-tal-ik strip]

Back

Bimetallic Strip

---

A strip made of two different metals bonded together that bends when heated due to their different expansion rates.

---

Example: The image shows how a bimetallic strip bends when heated or cooled, explaining thermal expansion.
