Brad investigated whether sea salt raises the boiling
point of water. He put 3 liters of water at 20oC and 1.5
cups of sea salt in a pot, heated the solution over 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 sea salt raises the boiling point of water by 5oC.
Where did Brad err in his experiment?
A.
B.
C.
D.
He did not boil a pot of water without sea salt
He did not conduct the trials at the same time
He waited until the water reached a rolling boil
He should have repeated the measurement several
more times
