You are testing an unknown liquid to determine its identity. First you heat the liquid and find that it turns to gas at 80 degrees Celsius. Then you add sodium to a small amount of the liquid to see if it reacts. Last you try to burn the liquid to see if it is flammable. Which physical property of the liquid did you test?

combustibility

ability to conduct electricity

melting point

boiling point

Vocaloid · Answer

Eliminate combustibility (which is a chemical property) and ability to conduct electricity (which is not tested in any of the experiment)

Between melting point and boiling point re-read the question to see if it’s a solid changing to a liquid (melting) or a liquid changing to a gas (boiling)
