When a piece of paper is soaked in oil,it becomes translucent but water does not have same effect on paper,why

Question

if possible also explain the molecular details

Answer 1

The reason oil makes paper translucent is because it soaks into the mesh of the paper and fills the air holes that were there to begin with. Light travels through the paper fibers and the oil at about the same speed which causes the light not to get bent around and scattered back to your eyes as much as it would if the paper had tiny air pockets in it. The more light that can travel through the paper, the more translucent it is.

The reason water doesn't have the same effect is because light doesn't travel through water at the same speed as it travels through the paper fibers. This difference in speed causes the light to be scattered back to your eyes making the paper look opaque.

Answer 2

I'm not sure. But my guess is it has to do with the relative size of the molecules, and also with what these liquids do to paper.

If you magnify a piece of paper, it looks like a mesh.

Water molecules are small. They penetrate in between the fibers of paper, making them fat and expanded. Every strand of the "mesh" becomes fatter. Naturally, this won't help th paper to become more translucent than it was.

It is just my guess that oil molecules, being large, will want to make room for themselves in between the fibers, thus pushing fibers in all possible direction, squeezing each and every one of them to become even thinner. Every strand of the "mesh" becomes thinner. You can see through mesh of thin strands.

Answer 3

Hard telling. It might have to do with the molecular size of the oil?

Answer 4

water and oil are two very different chemical compounds.

Oil is composed of fairly large molecules with very little energy holding them together, only their tremedous size keeps them in a liquid state at room temperature. oil also magnetically inert.

water is the exact opposite, very small molecules held together by tremendous hydrogen oxygen bonds, they are magnetically polar

Answer 5

The index of refraction of oil more closely matches the index of refraction of cellulose (paper fibers), than does the index of refraction of water.

Answer 8

paper absorbs oil - rock beats scissors- scissors beat paper
rock beats scissors - paper beats rock

Answer 9

because oil is heavier

Answer 10

why? because science explains it all
