Question

You are asked to determine the identity of an unknown liquid and can measure only one physical property. You heat the liquid and record that the liquid turns to vapor at 100°C.

Which physical property does this demonstrate?


A. boiling point


B. malleability


C. ability to conduct electricity


D. melting point

Answer 1

Boiling point because the vapor pressure of the liquid is equal to the atmospheric pressure

Answer 2

A. boiling point

Step-by-step explanation:

I'm not good at explaining science but...

Heating- keyword

I would take out b and c because you don't need heat for those.

When it's liquid, it would boil, not melt.

Vapor is also a sign of boiling.
