Thermos Engineering

Front

Kinetic Energy Noun

---

[ki-net-ik en-er-jee]

Back

Kinetic Energy

---

The energy that an object or particle has because of its motion, which is fundamental to energy transfer.

---

Example: A ball rolling down a slope demonstrates kinetic energy as it moves.

Front

Conduction Noun

---

[kuhn-duhk-shun]

Back

Conduction

---

The transfer of kinetic energy from one particle to another through direct contact or physical collision.

---

Example: Heating one end of a metal bar transfers thermal energy to the cooler end.

Front

Particle Noun

---

[pahr-ti-kuhl]

Back

Particle

---

A very small piece of matter that makes up all substances and can transfer energy through collisions.

---

Example: Particles collide to transfer energy, showing how matter interacts at a small scale.

Front

Insulation Noun

---

[in-suh-ley-shuhn]

Back

Insulation

---

The use of specific materials to reduce the rate of energy transfer between an object and its surroundings.

---

Example: A vacuum flask uses a vacuum and reflective surfaces to insulate and reduce heat transfer.

Front

Insulator Noun

---

[in-suh-ley-ter]

Back

Insulator

---

A material that is a poor conductor of energy and is specifically used to reduce unwanted energy transfer.

---

Example: The image shows how an insulator reduces energy transfer by limiting particle movement.

Front

Vacuum Noun

---

[vak-yoom]

Back

Vacuum

---

A space that is completely empty and contains no particles of matter, making it an excellent insulator.

---

Example: The vacuum between the flask walls prevents heat transfer, keeping liquids hot or cold.

Front

Criteria Noun

---

[krahy-teer-ee-uh]

Back

Criteria

---

The specific requirements or standards that a design or solution must meet in order to be considered successful.

---

Example: A checklist showing specific requirements a thermos design must meet to be successful.

Front

Constraints Noun

---

[kuhn-streynts]

Back

Constraints

---

The limitations or restrictions, such as cost, materials, or time, that affect an engineering design or project.

---

Example: The 'ASK' step identifies constraints like cost and materials in engineering design.

Front

Energy Efficiency Noun

---

[en-er-jee ih-fish-uhn-see]

Back

Energy Efficiency

---

The quality of using less energy to perform the same task, which helps to reduce overall energy waste.

---

Example: A house uses solar panels and insulation to save energy, showing energy efficiency.

Front

Dissolve Verb

---

[dih-zolv]

Back

Dissolve

---

The process where a solid substance breaks down into smaller pieces and mixes evenly into a liquid.

---

Example: Solute particles mix evenly into a solvent, forming a solution.
