The correct answer choice which is a physical property of matter is boiling point.
Polymers are long chains of <u>molecules</u>
The method which I would use to separate two liquids with different boiling points is <u>distillation</u>
The particles are located in the nucleus of an atom are protons and neutrons
The type of molecular model which is used to represent very large molecules like proteins is ribbon diagram
The methods which is used to separate a mixture according to the size of the particles are filtration and chromatography
<h3>What is a mixture?</h3>
A mixture is a substance which contains two or more constituents which can easily be separated by physical means
So therefore, the methods which is used to separate a mixture according to the size of the particles are filtration and chromatography
