A quantity of matter that is homogeneous throughout is called a

• A. Phase
• B. State
• C. Substance
• D. Mixture

Answer: (A)

A phase is a homogeneous portion of matter with uniform properties throughout. If a sample has the same composition, density, temperature, and other characteristics everywhere, it is one phase. That’s why a quantity of matter that is uniform throughout is described as a phase. A state refers to the form (solid, liquid, gas) of a substance and can exist in multiple phases under different conditions. A substance is a pure material with a definite composition and can occupy different phases. A mixture is a combination of substances and may be uniform or have separate regions, potentially containing more than one phase.
