Is liquifying nitrogen a chemical change?
It is a chemical change because it can change back if you refreeze the nitrogen and it changed the chemical.
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.
When liquid nitrogen boils at - 196 celsius is that chemical or physical changes?
The boiling of liquid nitrogen at -196 degrees Celsius is a physical change. This is because the change in state from liquid to gas does not involve a change in the chemical composition of the nitrogen molecules.
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.
Nitrogen gas react with hydrogen gas to form ammonia what are the reactants in this chemical reaction?
nitrogen gas and hydrogen gas

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 nitrogen change states a chemical or physical change?
Changing states of nitrogen, such as from a gas to a liquid, is a physical change because the chemical composition of nitrogen remains the same. It only involves a change in the arrangement of nitrogen molecules.
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 ..

Why is the electrolysis water classified as a chemical change but the freezing of water is not?
Freezing is a phase transition and does not change the chemical makeup of H2O. (melting restores). Electrolysis changes the chemical structure of the water, decomposing the H2O into oxygen (O2) and hydrogen gas (H2).
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
Why does liquid nitrogen exposed to air is a physical change?
When liquid nitrogen is exposed to air, it rapidly evaporates and turns into nitrogen gas. This process is a physical change because only the physical state of the substance is changed from liquid to gas, without altering its chemical composition.
Is a lake freezing a chemical change?
Yes, whenever something changes from liquid, solid or gas, It is considered a change in state.
What does not signal a chemical change color change or production of light and heat or production of gas or change in state?
A change in state does not necessarily indicate a chemical change. Melting, freezing, boiling, or condensing of a substance are physical changes that do not involve a change in the chemical composition of the substance.
