Question

Conductors are substances that allow electric current and heat to flow through them while insulators do not. To determine whether a substance was a conductor or an insulator, as student collected aluminium, copper, steel, and glass and followed the procedure below;

Fill a beaker with hot water
Fill another beaker with equal amount of cold water
Connect the beakers with the materials to be tested
After three minutes, record the temperature of water in each beaker
Repeat each set-up using each material

What is step 4 in the experiment?

Answers

Heat up the water in the beakers.
correct

Record the initial temperature of the water.
Record the initial mass of the beakers.
Graph the results.

Explanation

In the experiment, the student is trying to determine which of the materials is a good conductor and insulator, and as such he has to measure and record the initial temperature of each set-up before the experiment. This will allow him make a comparison with the temperature that will be recorded after three minutes and determine the material that loses or retains heat better.
