Question

Madison lives near the ocean. She’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. If Madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: (this is a mutable choice answer)

Answer 1

Temperature, air pressure, and humidity to name a few.

Answer 2

The variables to deal with are; temperature, humidity and moisture

Step-by-step explanation

A combination of the factors such as moisture in the air and salt in the air from the ocean can accelerate the rate of rusting occurring in areas next to the ocean. Water and salt can lead to rust on their own due to the redox reaction that will involve reduction of oxygen into hydroxide ions and oxidation of the metallic iron to iron cations.
