Which of these properties of an unknown liquid can be found using a beaker, a hot plate, and a temperature probe?
f oxygen level
g chemical composition
h boiling point
j density

Boiling point

Explanation:

If you want to find the boiling point of an unknown liquid, just use beaker, a hot plate, and a temperature probe.

Boiling is characterized by the rapid transition from liquid to gaseous, with the formation of vapors (bubbles) inside the liquid. As in fusion, there is a temperature (boiling point) at which a given substance changes from a liquid to a gaseous state. This temperature is the boiling point.

In the case shown in the question above, you will need to pour the liquid into the beaker and heat it up with the hot plate. With the temperature probe, you will mark the temperature that the liquid started to boil.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
