2. Pre Lab Discussion
The arrangement of atoms in the three states of matter are drawn as particle diagrams.
The 3 parts of particle diagrams represent 3 of our vocabulary words
n (the number of particles)= mass (g)
The box= volume (mL)
Arrows (vectors)= temperature (C)

3. Solid
Close together
Motion= vibrate

4. Liquid
Spread apart enough to slide
Motion= flow in one direction

5. Vapor (gas)
Very spread out
Motion= chaotic, going everywhere

6. Purpose
To determine the graphical relationship between time (min) and temperature (°C) for water. -What will happen to the temperature as the water is heated? Draw a prediction of how your graph will look, include labels and units.
Prediction

7. Materials (designate jobs for each group member)
Ice
Beaker
Thermometer probe (or alcohol thermometer)
LabQuest (LoggerPro3 software)
Ring stand
Clamp
Hot plate (or Bunsen burner)
Stirring rod
