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 else can I help you with?
Is liquid water a physical or chemical property?
Being liquid is a physical property. Being water (H2O) is a chemical property.
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.
Classify as chemical and physical change-freezing of water?
Freezing of water is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of water. The molecules in water rearrange to form a crystalline structure in the solid state but remain as H2O molecules.
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.
Is higher density the liquid state than in the solid state physical property of water?
Yes, the higher density of water in its liquid state compared to its solid state is a physical property known as anomalous expansion. Water reaches its highest density at 4 degrees Celsius in its liquid state, which is why ice floats on water.
When water is a liquid what is the physical state of nitrogen?
When water is a liquid, nitrogen is in a gaseous state. Nitrogen has a boiling point of -196°C, much lower than the freezing point of water, so it will be gaseous at room temperature when water is in a 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.
What is the Physical state of water at 15 degree Celsius?
water is a liquid aT 15oC Water is a solid (Ice) below 0oC Water is a vapour (steam) above 100oC.
What is a sentence with the word physical state?
the physical state is having problems.
Why does liquid nitrogen freeze?
Liquid nitrogen freezes into a solid state because its temperature decreases below its freezing point of -210 degrees Celsius (-346 degrees Fahrenheit), causing the molecules to slow down and form a solid. This transition from liquid to solid is a physical change that occurs due to the removal of heat energy from the nitrogen molecules.
Can a water gun shoot liquid nitrogen?
No, a water gun is not designed to handle or shoot liquid nitrogen. Liquid nitrogen is extremely cold and can cause serious injury if not handled properly. It is not safe to try to shoot liquid nitrogen from a water gun.
What will happen if you will add hot water to liquid nitrogen?
It depends on how much water, how hot it is, and how much liquid nitrogen there is. The water will initially cause the liquid nitrogen to boil; if there's enough water and it's hot enough, it may make the nitrogen boil explosively. However, if there's enough nitrogen, it will eventually freeze the water.
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.
Classify as chemical and physical change-freezing of water?
Freezing of water is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of water. The molecules in water rearrange to form a crystalline structure in the solid state but remain as H2O molecules.
What are the examples of a physical changes?
Change of the state of water from a solid (ice cubes) to liquid (water).
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.
