The result of the procedure is that the copper strip should go through oxidation.
<h3>How to explain the procedure?</h3>
The copper strip should be considered as the anode and the nail should be considered as the cathode.
The anode is the electrode of an electrochemical cell at which oxidation occurs. The anode should be + while the cathode should be negative. Both should be placed in the tank that should be filled with the electrolyte solution.

The physical property you measured is the boiling point of the liquid.
Therfore, if the liquid has a boiling point of 100°C, it turns from liquid state to vapor when you heat it up to 100°C.
To conclude, The liquid should be pure water. Because only pure water has a boiling point of 100°C, using this physical property, we can test whatever liquid ans see if it's pure water or not, this test is called the boiling point test.
