My Question
-What is the difference between a "phase of matter" and a "state of matter"?
Oh and if you could please help with this too:
Are the following Homogeneous or Heterogeneous?
1)14 kt. Gold
2)dishwater

States of matter: Solid, liquid and gas (plasma is the fourth state where the atoms are stripped of all the electrons).
Phase is a constituent of a state. For example, salt-sugar mixture is a solid state, two-phase material. Steel is a two-component (iron and carbon) or multi-component material with one or more phases.
A solution is a mixture of a solute like salt in a solvent like water and is a single phase system. A phase is a clearly identifiable aspect of a material.
14 Kt. gold is homogeneous alloy of gold and copper.
Dishwater? You mean a solution of soap or detergent in water? If yes, it is a homogeneous solution.

state and phase of matter are the same
14k gold is homogeneous
dish water is heterogeneous
