What metal conducts heat fastest:- Steel, Aluminum,
Copper or Brass?
Hypothesis
I think that Copper will be fastest conductor of heat because it has a weak core and will defuse quicker than normal metal. I think that Steel will melt the slowest because it is used for everyday equipment.
Method
Materials:
1x Tripod
1x Spirit Burner
4x Small wax buttons (Same Size)
1x Round wooden ring with 4 pieces of metal the same size and shape fixed equidistant to each other so that the point faced inwards and the indent was on the outside (See Figure 1). The metals were steel (S), Aluminum (A),Copper (C) and Brass (B).
1x Stop Watch
Method
Procedure:
We put small pieces of wax in the hollow on the ends of 4 strips of different metals that were fixed on a round wooden frame.
We heated the metal strips
We timed the melting of the wax
We recorded the times in a table
Results:
Conclusion: I was wrong on copper melting it melted last in equally with steel at 14 minutes and 18 Seconds but I was right with steel melting last because steel hardly made a turnout it hardly melted because steel is used to conduct hot experiments like making lava go hard into rock.
On average the wax melted in the following order:
1st Brass
2nd Aluminum
3rd & 4th Copper and Steel.
We noticed that copper and steel hardly did nothing the steel only started to crack from the inside but it did nothing except for staying completely still and doing nothing.
The wax melted fastest with the brass because the molecules are easer to move than in the other metals and this is what makes the heat travel through the metal. This is called “Heat Conduction”. Where the molecules are more difficult 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 in a crowd and the movement ripples outwards.
We use copper metal in electrical wiring because copper conducts electricity faster and it does it really well . Brass is used in taps because brass is stronger than copper. We use Aluminum in pots because it heats up the things in the pot much faster .We use steel is flasks so that heat doesn't escape
