Science

3. The energy an object possesses due to its motion.
5. The movement of particles (usually molecules) from an area of high concentration to an area of low concentration until they are evenly spread out.
7. The amount of matter in an object, typically measured in grams or kilograms.
10. The angle between an incoming light ray and the normal (perpendicular line) to a surface it strikes.
12. The vast expanse that exists beyond Earth’s atmosphere, including planets, stars, and galaxies.
13. The total energy of particles in a substance, including both kinetic and potential energy.
14. The process by which light or heat energy is taken in by a substance.
15. The transfer of heat through direct contact between particles of matter.
17. The rate at which an object covers distance, measured in units like meters per second (m/s).
18. A material that does not allow electricity or heat to pass through it easily.
20. The passing of light or heat through a substance.
22. A material that does not conduct heat or electricity well, therefore preventing the flow of heat or electricity.
23. The bouncing back of light rays when they hit a surface.

1. A material that allows heat or electricity to flow through it easily.
2. The transfer of heat through the movement of a fluid (liquid or gas) caused by differences in temperature.
4. A material that allows electricity or heat to pass through it easily.
6. The movement of water molecules through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.
8. Waves of energy that travel through space and carry electromagnetic radiation, including light.
9. The form of energy that causes objects to feel hot, measured in units such as calories or joules.
11. The bending of light rays as they pass from one medium to another.
14. The angle between a reflected light ray and the normal to the surface it reflects off of.
16. The movement of energy or matter from one place to another.
19. The transfer of energy through electromagnetic waves, such as heat or light, without the need for a medium.
21. A transparent object, often made of glass, that separates white light into its different colors through refraction.
