Recognize that a 'mixture' consists of two or more substances physically combined, and its composition can vary.
Know that a 'solution' is a type of mixture where one substance is dissolved uniformly in another, but its composition can still vary.
Identify that a 'colloid' is a mixture with particles dispersed throughout but not dissolved, also with variable composition.
Conclude that the term describing matter with a composition that is always the same is 'pure substance' because it has a constant and definite composition.
