Question

Why does butter make paper see through?

Answer 1

Very very very good question. Though after much thinking still i could not get it but i will try to explain.

When butter or for that matter any greasy or fatty substance like oil is applied on paper the fatty acids present in it act like a solvent and dissolve the organic matter that paper is made up of. ( if you put too much of oil on paper it will get torn/dissolved after a while). I think so thats it because when we apply butter/oil it seems to spread like a film /solvent on it.

Answer 2

Because of the oil that it contains. The oil saturates the natural fibres in the paper,and because it is so thin,it appears translucent. Bye

Answer 3

Answer 4
