Evaporation is a physical change; nitrogen remain nitrogen.
Physical change, as it goes from nitrogen liquid to nitrogen gas ... No chemical change takes place.
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.
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.
It is a chemical change because it can change back if you refreeze the nitrogen and it changed the chemical.
A liquid at normal temperatures and pressures is a physical change. When a substance changes from a solid to a liquid or from a gas to a liquid without any chemical reactions taking place, it is considered a 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.
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.
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 ..
Yes it is
liquid nitrogen will not freeze everything. Hydrogen and helium will remain a gas when exposed to liquid nitrogen.
The boiling of liquid nitrogen at -196°C is a physical change. During this process, the nitrogen molecules gain enough energy to overcome the intermolecular forces holding them together as a liquid, transitioning into a gas phase without undergoing any chemical reactions.
It is a chemical change because it can change back if you refreeze the nitrogen and it changed the chemical.
Sure, change from solid to liquid is a physical change
At -200 degrees Celsius nitrogen is a liquid.
physical change, its molecules are gaining energy and evaporating
