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.
If ethyl alcohol boils at 79 degrees Celsius a physical or chemical change?
Boiling of ethyl alcohol at 79 degrees Celsius is a physical change. It is a reversible process where the alcohol changes from liquid to vapor state without undergoing a chemical reaction.
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
When the boiling point of water is 100 degrees celsius is it a physical or chemical property?
The boiling point of water at 100 degrees Celsius is a physical property, as it is a characteristic of the substance related to its state of matter, specifically its transition from liquid to gas. Chemical properties, on the other hand, involve the substance's ability to undergo chemical changes or reactions.
Is something that boils at 20 degrees C chemical or physical?
Boiling at 20 degrees Celsius is a physical property. Chemical properties involve changes in the chemical composition of a substance, while physical properties describe the state or appearance of a substance without changing its composition.
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 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.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
If ethyl alcohol boils at 79 degrees Celsius a physical or chemical change?
Boiling of ethyl alcohol at 79 degrees Celsius is a physical change. It is a reversible process where the alcohol changes from liquid to vapor state without undergoing a chemical reaction.
Changes in properties of matter are called?
physical or chemical changes
Are state changes chemical or physical changes?
Physical Changes
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Is reacting a physical change or chemical change?
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
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 ..
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
