Does a nail become lighter when it rusts?

No, a nail does not become lighter when it rusts. Rust is actually iron oxide that forms on the surface of the nail, which can increase the overall weight of the nail due to the addition of oxygen atoms from the rusting process.

Why does iron weigh more after it rusts?

Iron weighs more after it rusts because rust is formed by the addition of oxygen from the surrounding environment. This increase in weight is due to the formation of iron oxide layers on the surface of the iron, which adds to the overall mass of the object.


When a part rusts it becomes?

When a part rusts, it becomes weakened and deteriorated due to the oxidation of the metal. This can lead to structural failure and potential safety hazards if not addressed. Regular maintenance and prevention methods are key to avoiding rust formation.


There are 10 grams of iron in a sealed container with moist air The sealed container with iron and moist air weighs a total 15 grams what is true after the iron rusts?

After the iron rusts, it will combine with oxygen from the air to form iron oxide. Since the total weight of the sealed container after the iron rusts is still 15 grams, the added weight will be the mass of the oxygen atoms that combined with the iron to form iron oxide.


When iron rusts does its weight increase or decrease?

Actually it doesn't affect its weight at all. During the chemical change that occurs when iron rusts, the weight does not change because weight never changes during a chemical reaction because nothing new is being created nor destroyed, only combined.

Yes, iron can be used to build a yacht, but it is unadvised. Since iron rusts in water and the weight of it just isn't profitable.


What happens to the weight of an iron nail after 3 days in salt water?

The weight of an iron nail may increase slightly after 3 days in salt water due to the absorption of some water and formation of rust on its surface, which adds weight. Additionally, the salt in the water can also contribute to the corrosion process.
