Pennies are made of copper and don't rust unless they are the zinc pennies issued in 1942 and 1943. However, zinc will not rust either. The so-called steel pennies minted during World War II were made of steel and coated with zinc. If the penny becomes damaged or if the zinc coating is compromised, the underlying steel will rust if exposed to the proper elements.
Pennies do corrode though.

What is the difference between saltwater and rainwater?
Rain water is fresh water and does not have salt. Saltwater is not fresh and does have salt.
Does sound travel faster in fresh water or salt water?
it depends on the circumstances. boat type, wind..... In a controlled environment where water temp,current, and wind are equal you will be faster in fresh water. this is because fresh water is less dense thus creating less resistance. on the other hand you float higher in saltwater which can also create less drag. However mathematically because of the resistance of saltwater you can calculate that you will be able to go faster in fresh water despite floating higher in saltwater. Its not much faster. I haven't calculated it but if I had to guess maybe 1-2% faster. A more dramatic example would be easier to understand. lets compare freshwater vs mud or somewhat diluted mud 50 50. its a lot easier to figure out which you will go faster in. My boat will practically sit on top of the mud. less drag right? This is what most people think saltwater does for them. How fast are you going to go in mud? Not hard to figure that out. there is too much resistance, you probably wont go anywhere. Apply this same logic to saltwater vs fresh and you can see that the more dense a solution is the more resistance it will have.
Does iron rust faster in vinegar saltwater or freshwater?
Zinc will corrode in vinegar faster than salt water
How does saltwater intrusion happen?
Saltwater intrusion is the movement of ocean water into fresh groundwater that causes contamination of the freshwater by salt. This is a process of nature and usually occurs near the coastlines where the fresh groundwater level approaches the same level as the sea.
Does salt water freeze faster than fresh water?
Salt freezes slower (i.e. at a lower temperature) than fresh water. Generally the greater the level of dissolved substances, the harder it is for ice crystals to form, so the greater the level of cooling required. Completely saturated saltwater freezes at -6°F / -21.1° C. == ==
Does saltwater sit on the bottom of a river?
NO, saltwater will dilute and blend in with the fresh water in a river. The faster the current, the faster it will mix in.
Does a teaspoon of salt dissolve faster in saltwater or freshwater?
