Classwork (10/16) p.4

1. Freezing, melting and boiling are examples of: physical changes or chemical changes (circle one). Explain how you know this.

2. Which state of matter has a indefinite volume and an indefinite shape?

3. In what state of matter are the molecules most tightly packed together?

Classwork (10/16) p.4

1. Freezing, melting and boiling are examples of: physical changes or chemical changes (circle one). Explain how you know this. Physical changes – ALL phase changes are physical changes

2. Which state of matter has a indefinite volume and an indefinite shape? Gas – Particles are so spread out it has no shape / volume

3. In what state of matter are the molecules most tightly packed together? Solid, they vibrate next to each other.

Classwork (10/16) p.4

4. In what state of matter do the molecules have the least energy?

5. When you cool down a substance, the molecules will: spread out

or get closer together (circle one).
