At normal atmospheric pressure, nitrogen is gaseous over the entire liquid range of water (and considerably below as well; the boiling point of nitrogen is about 77 K).

Can liquid nitrogen freeze the wind?
No. The wind is composed of a small amount of water vapor and about 20% oxygen and about 80% nitrogen. The water vapor may freeze but the oxygen and the nitrogen cannot freeze at the temperature of liquid nitrogen. Oxygen has a much lower freezing point than liquid nitrogen and if the nitrogen were to be frozen, liquid nitrogen is not cold enough to freeze it...sort of like trying to make ice using cold water.
What is the kid definition of physical state?
Physical state means solid, liquid, or gas. A gas is something like air. A liquid is something like water that you can pour. A solid is something like the floor or your chair.
Which physical property of water changes when it reaches melting point?
The physical property of water that changes when it reaches its melting point is its state of matter. At the melting point, water changes from a solid (ice) to a liquid form.
Is vapor a liquid a solid or a gas?
Water (H2O) comes in three different physical states; liquid, solid and gas. Water vapor is water in a gaseous state. Water vapor can be produced from the evaporation or boiling of liquid water or through the sublimation of ice. Typically water vapor is constantly being created by evaporation. Unlike the solid or liquid state of water, water vapor is not visible to the human eye.
What does liquid nitrogen look like?
At room temperature it is a colourless gas with no smell. Below minus 196 degrees C (its boiling point), it is a colourless liquid. It will not burn nor support burning, and will only react with other elements with difficulty. Pretty boring really! Look at the air you're breathing in right now. That's what nitrogen looks like, in its gaseous state. Nitrogen makes up almost 4/5 of the air we're breathing in. There's much less oxygen in regular atmospheric air than nitrogen. In liquid form, nitrogen is a clear liquid, much like water. This form of nitrogen is used for cryogenic purposes (freezing), and other applications, such as fighting T-1000 model Terminators.
When the water is a liquid what is the physical state of nitrogen?
At normal atmospheric pressure, nitrogen is gaseous over the entire liquid range of water (and considerably below as well; the boiling point of nitrogen is about 77 K).
What is the Physical state of water at 15 degree Celsius?
Liquid state
Is liquid water a physical or chemical property?
Being liquid is a physical property. Being water (H2O) is a chemical property.
Is the freezing point of water a physical state?
No it is the temperature at which water changes physical state from a liquid to a solid.
Is production of steam a chemical or physical change?
The change from liquid water to steam is a physical change in the state of matter. Evaporation is the term for a liquid becoming a gas.
Is rain turning to sleet a physical or chemical change?
A physical change. It came from water and is still water.Physical - the water changes from a gas,water vapour, to a liquid, rain.
Is the boiling of water until it becomes water vapor is a physical or chemical change?
It's a physical change. All changes of state (solid to liquid, or liquid to gas, for example) are physical changes.
What are the examples of a physical changes?
Change of the state of water from a solid (ice cubes) to liquid (water).
Is it physical or chemical when water freezes at 0 degree celsius?
When liquid water freezes to form ice, the chemical composition of water does not change. It will be H2O whether it is in liquid state or solid state. So it is a physical change and not a chemical change.
Why is the water cycle a physical change?
because during a water cycle only the state of the water molecules are changed i.e. first from liquid to vapour and then to solid (snow and hailstorm) or liquid (rain). since there is a change only in the physical state of water and there is no change in the chemical properties of the water molecule it is a physical change.
What is the texture of liquid nitrogen?
Liquid nitrogen looks like boiling water, since at the point of liquid nitrogen at room temperature, it is extremely hot.
Classify as chemical and physical change-freezing of water?
Physical. changes of state (solid, liquid, gas) are physical changes.
