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?

• Sample Y will boil at a lower temperature because it has more volume.

• Sample X will boil at a lower temperature because it has less volume.

• Whichever sample receives heat first will have a lower boiling point.

• Sample X and Sample Y will boil at the same temperature.

• I don't know.
