Federico has two samples of pure water—sample X and sample Y. Sample X has a volume of 1 L, and sample Y has a volume of 10 L. How do the boiling points of these two samples compare?

Question

A.
Sample Y will boil at a lower temperature because it has more volume.
B.
Sample X will boil at a lower temperature because it has less volume.
C.
Sample X and sample Y will boil at the same temperature.
D.
Whichever sample receives heat first will have a lower boiling point.

Answer 1

The correct answer is C. Sample X and sample Y will boil at the same temperature.

The boiling point of a substance is an intrinsic property that depends on the nature of the substance (in this case, pure water), not on the amount of substance or its volume. Both samples of pure water will boil at the same temperature, which is 100 degrees Celsius (at standard atmospheric pressure).
