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.
Whichever sample receives heat first will have a lower boiling point.
D.
Sample Y will boil at a lower temperature because it has more volume.

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 properties and not by the volume of the water. Both samples will boil at 100°C (at standard atmospheric pressure), regardless of their respective volumes.
