A lab group was given a candle, a match, a strip of cloth, tongs, and a metal can. They were asked to use these materials to model conduction, convection, and radiation. Develop a procedure they could use to do this.

The materials with which the lab group are to use for the model includes;

i) A candle

ii) A match

iii) A strip of cloth

iv) Tongs

v) A metal can

The processes the lab group are to model are;

a) Conduction

b) Convection

c) Radiation

The procedure the lab group can use to do this is outlined as follows;

1) Tie the piece of cloth around the metal can with a strip of the cloth extending past the bottom of the can

2) Hold the metal can in with the aid of the tongs

3) Light the candle with the match

4) Place the metal can over over the burning candle so that it does not touch the flame

5) While holding the can with the tongs, ensure that the strip of cloth hanging by the side of the can does not come in contact with the flame

Conduction

Conduction heat transfer is observed by the rising temperature of the tongs that is in the contact with the can

Convection

Convection heat transfer is observed by the rising temperature of the can that is placed in the path of the rising convection current from the candle wax

Radiation

Radiation heat transfer is observed by the shrinking of the piece of cloth placed beside the candle flame

Explanation:

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
