One observes a physical property.

No. Mixtures can be a single phase, such as in the case of salt water. This is a homogeneous mixture. A heterogeneous mixture would have more than one phase.
When the moon is not visible to observers on Earth, it is likely in its new moon phase. During this time, the side of the moon facing Earth is not illuminated by the sun, making it appear dark and invisible from our perspective.
The energy absorbed by one gram of water as it changes from its liquid phase into water vapor is known as the heat of vaporization. This energy is used to overcome the intermolecular forces holding the water molecules together in the liquid phase.
When the moon is fully visible to observers on Earth, it is said to be at its full moon phase. This occurs when the sun, Earth, and moon are aligned in a straight line, with the Earth in between the sun and moon. The full moon appears as a complete circle and is the brightest phase of the moon.
The two observers would each measure light to be the same. The speed of light is the same for all observers, regardless of their frames of reference.
As long as the observer is some place on the earth, his locationhas essentially no effect on the moon phase that he sees.
When the moon is fully visible to observers on Earth, it is in a phase known as the "full moon." During this phase, the entire illuminated side of the moon faces Earth, allowing us to see its surface details clearly. This occurs roughly once a month and is the result of the moon being positioned directly opposite the sun in relation to Earth. The full moon often appears bright and round in the night sky, captivating observers with its beauty.
A good example is water (H2O), where this one component can have 3 phases steam, water and ice.
Water and salt form a solution in the liquid phase.
That's it -- water. The stuff that comes out of a tap. Ice is the solid phase Water vapour is the gas phase
The liquid phase of water is called water.
