1 Icy Hot Lab Phase Changes of Matter (Physical Science)

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

8 Data Create a data table that has enough rows to write 50 time trials and 3 columns (probably will need 2 pages) Time Trials (.5min intervals) Temperature ( °C) Observations (changes seen) (# all the way to 25min)

9 Conclusion questions Sketch the graph from Logger Pro, connect the dots. Heating Curve
