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).
