It depends on the coin, however most will not as generally most coins do not contain iron (or steel). coins made from copper or tin will not rust ever.
salt will rust the coin faster thanfresh water
Because coins don't rust at all the last know coin was found a really long time ago. Also that coin don't have the certain needs that allows them to rust.
How long will it t take a quarter to rust in fresh water
Iron will rust more quickly in salt water than fresh freshwater. The salt in the water accelerates the corrosion process.
Yes they will.
Modern coins cannot rust, as they are not made of iron.
20 gauge galvannealed steel will rust faster in salt water compared to fresh water. The presence of salt in salt water accelerates the corrosion process of the metal, leading to faster rust formation.
It depends on what metals the coin is made from!
salt water cause of the salt particals in the water
the point of a hypothesis isn't to get it right but to gather knowledge you already have and make a guess. after u guess you test it and find out y u were right or wrong
A nail would probably rust faster in fresh water because rusting, also called oxidation occurs when large amounts of oxygen are forced into the metals pores, causing it to turn brittle.
Bronze will typically rust faster in salt water due to the higher presence of ions that accelerate the oxidation process compared to fresh water. Salt water contains more dissolved ions, such as sodium and chloride, which can enhance the corrosion of metals like bronze.
