Answer:
ACTIVITY TO SHOW CONDUCTION OF HEAT:
Materials required:
Metal scale
Pins
Glue
Candle
Experiment:
Take the metal scale and attach pins on the surface of the scale using the glue at regular intervals from one end.
Now, hang the scale in such a manner that the burning candle is present at one end of the scale. (See diagram)
Observation:
The glue melts and the pins start falling one by one.
The pins present closer to the candle and fall before the others.
Inference:
As heat flows through the metallic scale from the candle in to the other it melts the glue as a result of which the pins fall.
HEAT CONDUCTION IS PROVED !
