Particle Theory of Matter

Aim: To observe conduction along a metal rod

Method:
 1.Set up and light up a Bunsen burner
 2. Smear a small amount of petroleum jelly on the head on to the head of each drawing pin.
 3. Attach the drawing pins at even intervals along the length of metal rod
 4. C lamp one end of the metal rod to a retort stand.
 5. Position the retort stand so the unclamped end of the metal rod is in the Bunsen burner flame and start the stopwatch
 6. Record the time it takes for each pin to drop the table below

Results:
Discussion:

My group first heated the metal rod then we saw the pins dropping,.The reason why the pins drop down because the particles of the solid(the pins) are vibrating because of the heat that was transferred through the metal rod.Metal is a good thermal conductor.
