The physical properties I know of are the shape which are either a square or rectangle, the color which is either white or different colors. The chemical properties I know of are just before you make the paper, that's pretty much it...
Physical properties include characteristics of a substance that can be observed or measured without changing the substance's chemical composition. Examples include color, density, melting point, boiling point, and conductivity.

Phosphorous is an element. Here are some sentences.We studied phosphorous in science class today.Phosphorous ignites if you put it into water.Phosphorous is an interesting element.
physical properties can be observed w/o changing the chemical structure eg: physical state, colour, density, or electical conductiivity so baking soda is white.
Both sugar and salt are white, very small, and grainy like sand. A few chemical similarities are that salt and sugar are both water soluble, humans need both salt and sugar to survive, and both can burn.
