When you measure the boiling point of mercury, you are investigating a _______.

a. chemical change
b. chemical property
c. physical change
d. physical property

Answer 1

I think the correct answer from the choices listed above is option D. When you measure the boiling point of mercury, you are investigating a physical property. Boiling point is a physical property because it involves only a physical change. In boiling, the phase of the substance is only changed not the substance itself is changed.
