Answer:
1) all matter is made up of atoms and molecules 2) these tiny particles are always in motion; the higher the temp. the faster they move 3) at the same temp., heavier particles move more slowly then small particles
Explanation:
Answer:
melting is the process by which the a substance goes from a solid to a liquid as the temperature decreases.
freezing is the process by which a substance goes from a liquid to a solid as the temperature decreases
Explanation:
The variable we have to determine for this problem is the time. Since the given information is speed, we have to know the distance so that we can solve for the time. From literature, the distance between the Earth and the moon is 384,400,000 meters. Therefore,
Speed = Distance/Time
Time = Distance/Speed
Time = 384,400,000 m/ 3×10⁸ m/s = 1.28 seconds
