Verified step by step guidance1
Understand the key terms: A 'pure substance' has a fixed, uniform composition throughout, meaning its chemical makeup does not vary.
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.
