Conduction

Front

Heat Noun

---

[heet]

Back

Heat

---

The transfer of thermal energy from a warmer object or area to a cooler one due to a temperature difference.

---

Example: Heat flows from the hot red block to the cold blue block, showing thermal energy transfer.

Front

Energy Transfer Noun

---

[en-er-jee trans-fur]

Back

Energy Transfer

---

The movement of energy from one system, object, or location to another, which can occur through various processes.

---

Example: Heat flows from a hot object to a cold one, showing energy transfer by conduction.

Front

Thermal Energy Noun

---

[thur-muhl en-er-jee]

Back

Thermal Energy

---

The total internal energy of an object due to the kinetic energy of its atoms and molecules.

---

Example: Molecules in a hot area move to a cooler area, transferring thermal energy.

Front

Radiation Noun

---

[ray-dee-ay-shun]

Back

Radiation

---

The transfer of energy as electromagnetic waves, which can travel through a vacuum or empty space without particles.

---

Example: The Sun emits energy as electromagnetic waves that travel through space to Earth.

Front

Conduction Noun

---

[kon-duk-shun]

Back

Conduction

---

The transfer of thermal energy between particles that are in direct contact with each other, from hotter to colder areas.

---

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

Front

Convection Noun

---

[kon-vek-shun]

Back

Convection

---

The transfer of thermal energy through the movement of fluids, like liquids or gases, where warmer fluid rises.

---

Example: Warm water rises and cool water sinks in a pot, showing convection.

Front

Insulation Noun

---

[in-suh-lay-shun]

Back

Insulation

---

Any material that is used to reduce the rate of energy transfer, particularly heat, electricity, or sound.

---

Example: Heat moves from a hot area to a cold area, and insulation slows this transfer.

Front

Kinetic Energy Noun

---

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

Back

Kinetic Energy

---

The form of energy that an object or a particle has by reason of its motion.

---

Example: A cyclist moving downhill gains kinetic energy as they speed up.

Front

Engineering Design Process Noun

---

[en-juh-neer-ing di-zayn pro-ses]

Back

Engineering Design Process

---

A series of iterative steps that engineers follow to come up with a solution to a specific problem.

---

Example: A blueprint and lightbulb show planning and innovation in the engineering design process.

Front

Criteria Noun

---

[kry-teer-ee-uh]

Back

Criteria

---

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

---

Example: A checklist shows specific criteria that a design must meet to be successful.
