Announcements2.5 pts of extra

credit for coming for tutoring after school (up to 5 times / week)

Today’s Goal:Students will be able to describe phase changes in terms of particle movement and energy.Homework1. Finish Classwork if we

don’t (pages 4-5)due Wednesday

2. Phase Changes HW (p. 6-7)

due Wednesday


Objective: Students will be able to describe phase changes in terms of particle movement and energy

Bell Ringer (p. 14):1. Rank the 3 phases of

matter from greatest to least energy

2. Rank the 3 phases of matter from greatest to least spacing between particles

3. When you boil water does the temperature change during boiling?

questions wrong

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?


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.


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).
