Aim: What metal conducts heat the fastest: - steel, aluminum, copper or brass?

Hypothesis: I think that copper will be the fastest conductor of heat because it’s not very thick. I think that steel will be the slowest conductor of heat because it’s the thickest.

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: 1. we put small pieces of wax in the hollows on the end of 4 strips of different metals that are fixed on a round wooden frame.
 * 1) we heated the metal strips.
 * 2) we timed the melting of the wax.
 * 3) we recorded the times in a table.

Results

Fully liquid form. || 1st 51 sec || 3rd 6 min-15 sec || 2nd 2 min-11 sec || 4th 11 min-24 sec ||
 * || **copper** || **brass** || **aluminum** || **steel** ||
 * Time taken to met

Our group found that the melted in the following order: 1st: Copper 2nd: Aluminum 3rd: Brass 4th: Steel

Conclusion: My hypothesis was correct because I said that copper would heat the fasts and it did heat the fastest and I said that steel would heat the slowest and it was the slowest.

We use copper metal in electrical wiring because it conducts heat very well We use steel for flasks So that heat doesn’t escape. Brass is used in taps because it is a lot stronger than copper. Aluminum is used in pots and pans because it conducts heat better than other metals.
