Final answer:
Homogeneous mixtures can be in any phase, including gas, liquid, or solid.
Step-by-step explanation:
A homogeneous mixture may be in any phase, including gas, liquid, or solid. Homogeneous mixtures are substances that have a uniform composition and properties throughout, regardless of their phase. For example, a saltwater solution is a homogeneous mixture in the liquid phase, air is a homogeneous mixture in the gas phase, and steel is a homogeneous mixture in the solid phase.
