Physical. Anything that can be separated by physical means is a physical change, and you can separate oil from vinegar by skimming it off the top. You are also not making a new substance. In order to have a chemical reaction occur you must produce a new substance, not just a mixture. For example, vinegar and baking soda will produce carbon dioxide gas.
Oil and vinegar will not react with each other; they just form a heterogeneous mixture. Because there's no chemical reaction, it is just a physical change, because no new substance is produced.
Mixing is a physical process.

Yes?
Mixing vinegar and sugar creates a mixture. There is no chemical reaction.
Yes, when you add an acid, like vinegar, to milk a chemical reaction occurs. The acid causes milk to curdle. In fact, by adding vinegar to milk you can make cheese! http://www.wikihow.com/Make-Cheese-at-Home
chemical. when a reaction is undertaken that changes the structure of a substance and creates a new substance it is a chemical reaction. a gas is created during the reaction and a new chemical compound (sodium acetate) is left behind leaving neither of the previous elements present.
Its a physical change as there is no reaction.
Without a chemical reaction it is a physical process.
You can get a chemical reaction by mixing baking powder and vinegar together.

No, because it just change to liquid
It is a chemical change
physical- there's no chemical change.
The act of mixing chemicals is a physical process, not a chemical reaction. Mixing chemicals together may, or may not, allow a chemical reaction to proceed, depending on the nature of the chemicals being mixed.
