Tom investigated whether sugar raises the boiling point of water. He put 2 gallons of water at 20°C and 2 cups of sugar in a pot, heated the solution
over a flame and measured the temperature when the water reached a rolling
boil. He repeated the experiment three times and recorded the same result
each time. He concluded the sugar raises the boiling point of water by 5°C.
Where did Tom err in his experimental design?
A He did not conduct the trials at the same time.
B He waited until the water reached a rolling boil.
CHe did not boil a pot of water without sugar
Dhe should have repeated the measurement ce eral more times
