2. Copper consumed less time, that is, 15 seconds to melt the section of wax than the other metal pots, which signifies that it is a good conductor of heat than the others. Thus, the copper pot would be good for cooking food briskly.  

After evaluating the results and observations in an experiment, the conclusion was made that pots made of copper are best for cooking foods.
