Particle Theory Of Matter- Conduction

2 May Wednesday 2018

Conduction is a term used to describe the flow of heat through an object. Objects that are good at conducting heat are called thermal conductions. Metals are thermal conductors, but plastics, fur, wool, and gases are usually poor thermal conductors. Poor thermal conductors are called thermal insulator.

Aim: To observe conduction along a metal rod.

Equipment:  A metal rod, retort stand clamp, bunsen burner, petroleum jelly, 5-10 pins, a stopwatch.

Method:
1. Set up and light a Bunsen Burner.
2. Smear a small amount of petroleum jelly on to the head of each drawing pin.
3. Attach the drawing pins at even intervals along the length of the metal rod.
4. Clamp 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 flame and start the stopwatch.
6. Record the time it takes for each pin to drop in the table below.

Pin Number	Time to drop (s)
1	1min   13sec
2	4min   24sec
3	6min   25sec
4	8min   24sec
5	10min 31sec

So this is the experiment record for the conduction the pin number represents that pin one had this much time to drop and other as well etc. So the time as well the first pin dropped 1min 13sec and other pins dropped at the different timing as well. I have the picture as well which my group mate took it...

So this is the Image of the experiment and this is how it looks...













What I m I learning??
I learning to improve on my work and to know how to do experiments.

What did I improve on??
I improve on my doing experiments and getting information while the experiment is going on.

What I m I wondering??
I m wondering if we do an experiment we didn't do before that's what I m wondering now.
