An investigation involves determining which metal is better for making pots that will cook food faster

Good luck on the investigation? What is the question lol

Pots made of copper are better than those made of iron. Copper is malleable and heats up much faster than iron. Copper will heat up faster than iron if it is a better conductor.

Explanation:

Copper is the best heat conductor of any material used to make cookware. It heats rapidly and evenly and cools down as soon as it's removed from the heat, giving you maximum control over the application of heat.
