Is oxygen an example of a phase?
Oxygen is an example of one of the four phases of matter, it being of a gaseous phase. Phase is simply another term for 'state.' Liquid, Solid and Plasma being the others.
Why are some atoms or molecules in liquid form and not a solid?
The atoms and molecules in liquids move in a random pattern relative to one another instead of being in a solid form due to the intermolecular forces of attraction. The intermolecular forces are too weak to hold onto the molecules in a solid form.
What does it mean when glucose is being oxidized?
Oxygen is being reduced.
What are the variables for oxygen BEING slpit into hydrogen?
Oxygen cannot be split into hydrogen.
What happens to a substance when it dissolves in a liquid?
The molecules of the substance are totally dispersed in the liquid forming a homogeneous solution, intermolecular forces being practically annulled.
Do inter-molecular forces occur as a result of being in the liquid state or does a liquid state exist because of inter-molecular forces?
The liquid state is caused by intermolecular forces.
Why are some rockets fueled by liquid hydrogen and liquid oxygen?
unlike solid fuel, liquid fueled rockets are capable of being throttled, shut down, and restarted.
Why is oxygen needed by rockets and how do they get it?
Oxygen is used in liquid-fueled rocket motors as a combustion product, usually in conjunction with liquid hydrogen as well. In space, Oxygen is extremely thin at extreme altitudes, and it only occurs in space at the molecular level. It isn't enough to sustain the combustion of a liquid-fueled rocket motor once it enters the upper atmosphere without being fed liquid oxygen.

How can you get liquid oxygen using liquid nitrogen?
Liquid nitrogen is colder than liquid oxygen. You use the liquid nitrogen to chill the oxygen in the air and liquid oxygen will form. Liquid water and dry Ice (CO2) should also form due to their presence as well, but not in large quantity. WARNING!! High concentrations of oxygen should be considered dangerous. When exposed to a small ignition source, it can cause flammable materials to combust much like an explosion, and will cause normally non flammable materials to burn readily. Human flesh burns better than wood after being exposed to 100% oxygen for a period of time. Please be careful.
Why liquid can be compressible?
It has to do with the density of the molecles that make up the liquid. Water can not be compressed due to the hydrogen and oxygen molcules being so densly formed. There is also what is called heavy water that is where the compound has an extra oxygen atom.(H2O2)
When an aircraft is being serviced with liquid oxygen (LOX) a vehicle operator must maintain from the aircraft?
25 feet

How are the molecules in a liquid arranged?
by the molecule being forced in a position by strong forces. they can not pass each other no matter what by mr awesome
How do rockets off?
rockets take off when gases are shot out of the opposite direction with great force. The gases are conctrated by being forced through a small nozzle Liquid hydrogen and liquid oxygen is the fuel.
How solid act like a liquid?
Surface tension-Attractive forces cause particles on the surface of a liquid to pull together and resist from being pushed apart. These particles on the surface are pulled toward the center of the liquid and and sideways along the surface. There are no liquid particles above to pull on them. Particles under the surface are pulled in all different directions. Surface tension is the uneven forces acting on the surface particles of a liquid. Surface tension causes a liquid to act like it has a thin film stretched across the surface.
The shape of a liquid depends upon its?
A liquid takes the shape of its container.
