Objective: Students will be able to convert between metric units.

Bell Ringer (p. 15):1. If you are moving 3 m/s for

3s how far do you travels??2. What are the purpose of

units?3. How long do you study for

this class on a daily basis?

Have your homework out (page 7-8 and classroom materials) in preparation for a stamp.

Cornell Notes: Lab Review

Time

Phase Changes are flat because they

occur at a constant temperature

During a phase change you have a

mix of the two phases.

Kinetic Energy increases when Temperature

increases

Potential Energy increases during phase

changes

Lab

Post-Lab Questions:

1. What does the line look like on your graph when temperature is changing?

2. What does the line look like when temperature is not

changing?

3.What does the first flat region represent? What does the second flat region represent?

Melting, Boiling

4. At times (flat regions of your graph), why does the temperature of a substance remain constant, even

though energy is being added?

5. Label each segment of your graph, write which phase

of matter is for each segment and for phase changes say what type of phase change is occurring (freezing,

boiling, etc.)

6. During which phase were the water molecules the most free to move around? How could you tell? Can you

relate this to kinetic energy?

Lab

4. At times (flat regions of your graph), why does the temperature of a substance remain constant, even

though energy is being added?Phase Change; heat is being used to increase

potential energy by spreading molecules apart

5. Label each segment of your graph, write which phase of matter is for each segment and for phase changes say what type of phase change is occurring (freezing,

boiling, etc.)

6. During which phase were the water molecules the most free to move around? How could you tell? Can you

relate this to kinetic energy?Gas, because they leave the beaker! High movement =

high kinetic energy
