What form is used during post exercise reporting phase to list observations?
Observers/After Action Reports Form/Card
Do mixtures always have more than one phase Why?
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.
How are moon phases affected by the observers location?
As long as the observer is some place on the earth, his locationhas essentially no effect on the moon phase that he sees.
What would two observers one stationary and one moving each measure for the speed of light?
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.
What is the phase of the mixture of water and salt?
Water and salt form a solution in the liquid phase.
What is the liquid phase of water?
That's it -- water. The stuff that comes out of a tap. Ice is the solid phase Water vapour is the gas phase
What is a one phase one component system?
A good example is water (H2O), where this one component can have 3 phases steam, water and ice.
When one observes the phase of matter of water one observes a property of matter.?
A physical property.
What is the liquid phase?
There are three states of matter. they are solid , liquid and gas. A substance is said to be in a phase when it exhibits that state of matter. Ice is water in the solid phase. Water is ice in the liquid phase. Water vapour/steam is water and or ice in the gaseous phase.
When on observes the phase of matter of water one observes a?
Physical property of matter
What happen when water vapor from the hot water cools?
A change of phase; from gas phase (water vapors) to liquid phase; the phenomenon is called condensation.
During the phase called the new moon the moon is not visible to observers on Earth. Why not?
The moon is between the sun and earth and reflects light back toward the sun
