What is the difference between physical property and chemical property?
The way I remember the difference, is: a physical property is a property that you can observe without changing it (or observe without a chemical reaction). So properties like melting point, boiling point, density, color, hardness are all physical properties. A property like 'reacts with water' could only be observed by performing the reaction to observe the change.

What is the comparison between Rene Descartes' and John Locke's theory of substance?
Descartes had a dualist substance theory and believed that there were two substances, the mind and the body. Locke also believed that there were spiritual substances and physical substances, but his theory of substance relied on the substratum, a characterless thing that contains the characteristics we observe. Since we cannot observe substance, Locke believed we could not know anything about it.
