A beaker contains 30 milliliters acetone that boils at 56 °C. What is the boiling point of half of this acetone?

a) Half of 56 °C since boiling point is an extensive property
b) Half of 56 °C since boiling point is an intensive property
c) 56 °C since boiling point is an extensive property
d) 56 °C since boiling point is an intensive property

c) 56 °C since boiling point is an extensive property

Boiling point is a physical property of a substance that does not change based on the amount of substance present. Therefore, half of the acetone will still have a boiling point of 56 °C.
