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). Classwork (10/16) p.4 4. In what state of matter do the molecules have the least energy? Solid 5. When you cool down a substance, the molecules will: spread out or get closer together (circle one). p. 5 question 6 LIQUID deposition SOLID sublimation GAS Classwork Page 5 7.
