Making a Thermometer
Observation:
The height of the liquid in the straw increases when the bottle is placed into
hot water.
The height of the liquid in the straw decreases when the bottle is placed into
cold water.
Conclusion:
Bowl of hot water:
Temperature Liquid molecules Expansion Increase the
of liquid spread and of liquid height in the
increases molecules
spaces increase straw
Bowl of cold water:
Temperature Liquid Contraction Decrease the
of liquid molecules close of liquid height in the
decreases molecules
and spaces straw
