Question

Plan an experiment to find out if an iron nail rusts more quickly when it is warm than when it is cold.

Answer 1

Answer:

Temperature Changes

Hypothesize whether cold or warm air temperatures will affect the rate at which rust forms on iron nails.Gather nine iron nails and three beakers or glass containers of the same size. Place three nails into a container filled with tap water. Place three nails in a container and fill with ice cubes. Place the remaining nails in a container filled with tap water and place under a heat lamp. Leave all three containers uncovered in an undisturbed area and observe daily for one week. Ice must be added to the second container frequently to maintain a cold environment throughout the experiment. Oxygen, the primary component of rust formation, combines with other elements, including iron, more readily at warmer temperatures, so the nail under the heat lamp should rust first, while the nail in ice should be the last to form rust on its surface.
