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 ammonia boiling a chemical or physical change?
Physical change.. think of it as it changing state not the substance
Silver melts at 961 Celsius Is it chemical change or physical change?
This is a physical change because you are changing it from a solid to liquid
Is water condensing a physical or chemical change?
Water condensing is a physical change. It is a change in state from the gaseous phase (water vapor) to the liquid phase (liquid water) without any change in the chemical composition of water molecules.
Is melting copper an example of chemical change?
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
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 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.
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 boiling nitrogen in a laboratory a physical or chemical change?

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 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 the nitrogen cycle a physical or a chemical change?
The nitrogen cycle involves both physical and chemical changes. Physical changes include nitrogen fixation by bacteria and nitrification, while chemical changes include denitrification and ammonification.
Is pouring liquid a chemical change or physical?
A physical change.
Is liquid to gas chemical change?
No, the change from liquid to gas is a physical change, not a chemical change. In this process, the substance's molecular structure remains the same, only its physical state changes from liquid to gas.
Is liquid to a gas chemical or physical change?
it is a change of state, a physical change.
Is changing liquid to gas a chemical change or physical change?
physical change
