T1+Science-Melting+Wax

Aim: what metal conducts heat the fastest : aluminium, copper or brass?

Hypothesis:

I think that brass will be the fastest conductor of heat because it is weaker than the others.

I think that aluminium will be the slowest because it is stronger than the others.

Method: Materials:

1x tripod 1x Spirit burner 4x Small wax buttoms ( Same size ) 1x Round woode ring with 4 pices of metal the same size and shape fixed equidistant to each other so the point faced inwards and the indent was on the out side. The metals were steel(s), aluminium(A), copper(C) and brass(B). 1x stop wath

Method: procedure:

we put small pices of wax in the hollows on the ends of 4 strips of different metals that we fixed on the round wooden frame. We heated the metal strips. we timed the melting of the wax. we recorded the times in a table.

Results Our group found out that the wax melted in the following order 1.Copper 2. Aluminium 3. Brass 4.Steel

Conclusion

my hypothesis was wrong because i said brass was the the 3rd to melent and i was wrong for the slowest aswell because the steel was the slowest.

The wax melted faster with the copper because the molecules are esier to move than to the other metals and this is what makes the heat travel trough the metal this is called heat conduction were the molecules are more difficulte to move, heat takes more time to move through it.

Conduction occurs when the molecules bump against each other and cause more movement. It is like pushing someone who trips and pushes another person ia a crowd and the movement ripples outwards.

=
We use copper metal in pots and pans because we want to heat food we use steel in pipes and hot water cylinders so that heat doesn’t burn our fingers. Brass is used in tapes because brass rust. Aluminum is used in pots because we want to cook our food. All of these metals do get hot after a while such as terne. =====
