What phase is liquid nitrogen in at room temperature?
Liquid nitrogen is liquid.
What is the solvent and solute in liquid nitrogen?
There is neither a solvent nor solute in liquid nitrogen as it is not a solution. Liquid nitrogen is pure elementalnitrogen in liquid form.
What if liquid nitrogen was poured on the floor?
Liquid nitrogen is quickly evaporated.
Is liquid methane colder than liquid nitrogen?
No, at their boiling points liquid nitrogen is colder than liquid methane.
What is difference in volumes between liquid nitrogen and solid nitrogen?
is there a chemical difference between the solid and liquid states of nitrogen
Why does liquid nitrogen exposed to air is a physical change?
Evaporation is a physical change; nitrogen remain nitrogen.
Is liquid nitrogen that boils AT - 196 degrees Celsius chemical or physical?
Physical change, as it goes from nitrogen liquid to nitrogen gas ... No chemical change takes place.
Is liquid nitrogen boiling in a refrigerator a physical or chemical change?
It is a physical change, a change in phase from liquid to gas (evaporation). The nitrogen is chemically the same at the lower liquid temperature, but has some different properties because of its ability to absorb heat. If you cool the nitrogen gas , it will turn liquid again.
Is liquid nitrogen used in refrigerators for cooling?
No. Refrigerators use a substance called Freon that can readily change from liquid to gas to liquid, moving heat from inside the fridge to the outside. Liquid nitrogen is FAR too cold, and requires too much energy to make the change from gas to liquid.Yes, liquid nitrogen is used in refrigerators. Nitrogen is a diatomic gas. The two nitrogen atoms are bond with a triple bond.
Is liquid nitrogen supposed to be left on the skin after treatment?
Nitrogen must be cooled to a very low temperature to become liquid nitrogen. At room temperature, liquid nitrogen will change from the liquid phase to the gas phase. Therefore, if the skin is treated with liquid nitrogen, the liquid nitrogen will almost instantly become a gas and evaporate away from the skin. It is impossible to "leave" it on the skin, as this reaction is almost instantaneous and no liquid nitrogen is left behind.
Is liquid nitrogen evaporates after being poured on the floor a physical change?
Yes it is
What phase is liquid nitrogen in at room temperature?
Liquid nitrogen is liquid.
Does nitrogen change from a liquid to a gas at the same temperature at which water changes from liquids to a gas?
No it can not, their boiling points are vastly different.-----------------------------------------------------------------------------------Well, yes but the change will be explosive.If you poured liquid nitrogen into boiling water, all the liquid nitrogen would become gas and spray the remaining liquid boiling water in all directions.If you poured boiling water into liquid nitrogen, all the liquid nitrogen would become gas and spray the remaining liquid boiling water in all directions.Please don't try this, you will be severely injured!!!!!!
Why is it an advantage to transport nitrogen as a liquid rather than as a compressed gas?
The key to storing nitrogen as a liquid is that we need to compress and cool the nitrogen to cause it to change state from a gas to a liquid. By doing this, we can store a lot of nitrogen in a small volume compared to trying to store it as a gas.
What will be the state of liquid nitrogen after boiling?
when the liquid nitrogen is boiled then it will turn into nitrogen gas.
Is boiling nitrogen in a laboratory a physical or chemical change?
Compression of nitrogen or any gas does not alter the chemical property...only changes involve in physical properties... On compression the gas molecules are come into more close..so it is pressurized..not change its chemical property...and whenever chances is come it s expand ..
Is liquid nitrogen an element or compound?
Liquid nitrogen is an element.
