Question

metals are used in many products because of the characteristic properties that most metals have. which product requires the high luster of metals in order to work?
mirrors
pots and pans
food wrap
circuit boards

Explanation:

Mirrors rely on the high luster (ability to reflect light) of metals (like silver - coated layers) to function. Pots and pans use metals for heat conductivity. Food wrap uses metals (like aluminum) for malleability and barrier properties. Circuit boards use metals for electrical conductivity.

Answer:

mirrors
