Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
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.
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
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.
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
The changes from A to B and from B to C are physical changes. Physical changes do not alter the chemical composition of the substances involved. In this case, the changes are likely related to states of matter or physical appearance, rather than chemical composition.
well you know.......... why dont u tell me
Both chemical and physical changes involve a transformation of matter. In physical changes, the substance's chemical composition remains the same, while in chemical changes, new substances are formed as a result of a chemical reaction. Both types of changes involve the absorption or release of energy.
There are no physical changes. there are only chemical changes.
They both are different kinds of air.
physical or chemical changes
Physical Changes
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical 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.
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.
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.
Chemical and physical changes are part of methods applied in science.
