Kinetic Energy States Worksheet
⚡ Part 1: Multiple Choice - Kinetic Energy and States
1. Which state of matter has the HIGHEST kinetic energy?
Solid
Liquid
Gas
All have the same kinetic energy
2. In which state are atoms and molecules packed most tightly together?
Solid
Liquid
Gas
They are equally packed in all states
3. What happens to kinetic energy when ice melts into water?
Kinetic energy decreases
Kinetic energy increases
Kinetic energy stays the same
Kinetic energy disappears
4. Which properties do gases have? (Check all that apply)
High kinetic energy
Definite shape
Particles spread far apart
Takes shape of container
✓ Part 2: True or False
5. _____ Molecules in a liquid have more kinetic energy than molecules in a solid.
6. _____ Atoms in a gas move very slowly because they have low kinetic energy.
7. _____ When you heat water, you are adding kinetic energy to the molecules.
8. _____ Solids have definite shape because their atoms have very little kinetic energy.
✏️ Part 3: Short Answer
9. Explain why gases fill the entire space of their container. Use the words "kinetic energy" and "molecules" in your answer.
10. Fill in the blanks: In order from lowest to highest kinetic energy, the three states of matter are ________, ________, and ________.
11. Compare the kinetic energy and particle movement in ice cubes versus steam. Explain the differences.
12. When you add heat to a solid, what happens to the kinetic energy of its atoms? How might this change the state of matter?
