Examining Spider Genes

Front

Molecule Noun

---

[mol-uh-kyool]

Back

Molecule

---

A group of atoms bonded together, representing the smallest unit of a chemical compound that can participate in a reaction.

---

Example: Atoms of hydrogen and oxygen bond to form a water molecule.

Front

Kinetic Energy Noun

---

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

Back

Kinetic Energy

---

The energy that an object or particle possesses due to its motion; faster movement results in more kinetic energy.

---

Example: A cyclist speeds down a hill, gaining kinetic energy as they move faster.

Front

Temperature Noun

---

[tem-per-uh-cher]

Back

Temperature

---

A measure of the average kinetic energy of the individual atoms or molecules that make up a substance.

---

Example: Molecules in a hot area move faster than in a cold area, showing temperature differences.

Front

System Noun

---

[sis-tuhm]

Back

System

---

A set of interacting or interdependent components that are being studied, forming an integrated whole for scientific investigation.

---

Example: The solar system is a system where planets orbit the sun, showing interaction and integration.

Front

Collision Noun

---

[kuh-lizh-uhn]

Back

Collision

---

An event where two or more bodies exert forces on each other in a short time, causing a transfer of energy.

---

Example: Two spheres colliding to show energy transfer during a collision.

Front

Heat Noun

---

[heet]

Back

Heat

---

The transfer of thermal energy from a hotter object to a colder one because of a difference in their temperatures.

---

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

Front

Equilibrium Noun

---

[ee-kwuh-lib-ree-uhm]

Back

Equilibrium

---

The state in which a system is stable because energy is distributed evenly and no net change occurs over time.

---

Example: A seesaw balances when weights on both sides are equal, illustrating equilibrium.

Front

Thermal Energy Noun

---

[thur-muhl en-er-jee]

Back

Thermal Energy

---

The total kinetic energy of all the moving atoms and molecules that make up a substance or object.

---

Example: Molecules moving from a warmer area to a cooler area, showing thermal energy transfer.
