Answer:

1. Sorry I don't know

2. If oil is rubbed on a sheet of paper, it becomes transculent.

Answer 2

Answer:

When a white sheet or paper is stained with oil it becomes transparent because oil raises the transmissivity of light. It makes the paper more amorphous. 2) Both oil and paper have a similar refractive index so when oil fills the air gaps between paper and air then light is more easily transmitted through the paper.
