Answer:

• A pure substance is one which is made up of only one kind of particles.
• These particles may be atoms or molecules.

• In fact, all the elements and compounds are pure substances because they contain only one kind of particles.
• A pure substance is homogeneous throughout its mass.
• A pure substance cannot be separated into other kinds of matter by any physical process.

• A pure substance has a fixed composition as well as a fixed melting point and boiling point.
