# Most pennies do not rust because they are not made of ferrous metal. They're either copper or copper-plated zinc.
# However U.S. cents struck in 1943 were made of zinc-coated steel. When the zinc wore off, the coins did rust. # Pennies wont rust mostly because they corrode and oxidize. # They tend to turn green once oxidized or the penny looks vary dirty.

Factors that promote rust?
An iron material can easily rust in the presence of air and water. For example if an iron nail is half dipped in water and the rest of the nail is open in the presence of air then the nail can easily rust.
Does 20 gauge galvannealed steel rust faster in salt water or fresh water?
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.
When putting iron nails into sugar salt or tap water which water would rust the nail quicker?
It will rust faster in a salt water base and it will also rust faster in a tap water base not a sugary or a pop type, they have a slower fashion of rusting.
Will a quarter rust faster in salt water or fresh water?

Will Iron rust faster in soft water pH 7 or in humid air?
the iorn will rot in humid air but in soft water ph7 it will just rust
What water will rust the fastest cold or hot water?
warm water will rust metal faster
Does a nickel rust faster in cold water or hot water?
A nickel would rust faster in hot water compared to cold water because the higher temperature accelerates the chemical reactions involved in the rusting process. Warm environments generally promote faster oxidation and corrosion of metals.
Which water rust a coin faster salt or fresh water?

Does rust happen faster in cold or hot temperatures?
Rust generally occurs faster in hot and humid conditions because higher temperatures accelerate the chemical reactions that lead to rust formation. Cold temperatures can slow down the process, but when moisture is present, rusting can still occur over time.
Will a nail rust faster in soil or water?
A nail will rust faster in wet soil than water, but if the soil is not wet , the nail will rust faster in water. I hope this answers your question. Bye, Annette Pfohl
What will make a nail rust faster in 3 liquds watervinegarsprite?
water would make a nail rust faster because nails rust faster in water or any acidic liquads. As I been told
What liquid causes an iron nail to rust faster water or coke?
coke will make it rust faster
Will a nickel rust faster in salt water or regular water?
i believe the nickel wil rust more faster in salt water do to the variety of minerals. Also it doesn't rust that fast do to corrision
Which liquid will rust a penny faster vinigar or salt water?
Salt water will rust a penny faster than vinegar because salt water is an electrolyte that enhances the electrical conductivity, accelerating the oxidation process on the surface of the penny.
What water makes iron rust faster?
Salt water.
Does iron react in cold water?
