Science Lab Experiment:
Demonstration: Heating Water
Object: To learn what happens to the temperature of water as it is heated and to
draw a graph relating temperature to time.
Materials: water, electric heater, thermometer, beaker
Diagrams:
Method: The materials were set up as shown in the diagram. The water was heated
and every minute the temperature was recorded until the water boiled.
Observations: The temperature was seen to rise slowly at first and then increase
rapidly, until the water was almost boiling. The rise in temperature
then slowed.
Conclusions: It was concluded that water tends to absorb heat, causing a gradual
increase in temperature at first.
