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

Answer 1

The correct answer is:

A. Sample X and sample Y will boil at the same temperature.

The boiling point of pure water is determined by its chemical composition and is approximately 100 degrees Celsius at standard atmospheric pressure. The volume of the water samples does not affect the boiling point, so both samples X and Y will boil at the same temperature.
