ive been doing wanting to do this experiment on corrosion so i finally am doing it and im trying to find out if density affects the corrosion rate??

does the density of a rod affect how much it corrodes??

Corrosion of metals is not linked with density. A metal corodes when it loses electrons by them binding onto oxygen, sunch as iron oxide (rust). In simple terms, a metals tendency to oxidized is most highly dependent on ability to lose electrons. The one factor that effects this the most is what orbital is its valence electrons (the electrons in the outermost shell) in. A very large atom with few valence electrons will be highly likely to corrade, due to the lectrons small attraction the the nucleas. This is an oversimplified answer, but in short, density has little to nothing to do with corrosion, except for maybe teh fact that I very porous metal (one with lot's of hole) would have more surface area to corrode.

The density of a rod depends upon the chemical composition, metallurgical treatment received etc., and thus the change in chemistry, grain size, heat treatment, stress levels etc. affect the corrosion rate.

Even the same material processed differently but with the same density may corrode at different rates. So, your question needs to be reframed with this understanding.

an ecosystem can maintain a certain population and for the earth we are about there with 6 billion alive. population density does not affect the ecosystems ability to hold that size but it does effects the populations ability to gain access to food as the higher the density the better the transport and distributions the populations must use to deliver the food and remove wastes. if there was a breakdown of society the ecosystem can maintain the same population but those in high density situations would suffer as they would lose access to food,water and waste disposal while those in rural areas would basically be unaffected but have an large excess of food! if society is breaking down move to the country to increase your survival. with higher population densities the birthrate tends to be higher are people are more likely to mix however as the population density increases linearly nature has its own inbuilt population control in that the incidence of disease and homosexual tendencies will increase proportional to the square of the population density making it a self limiting factor.

Changing density is very hard to do, therefore hard to consider. However, without changing the density of the material (like iron) you can change the ratio of the surface area to the volume which would be very low for a solid sphere while the same volume of iron as wire, screen, chips, or dust would have much greater area and corrode faster.

duh uh! size doesnt count in density.
