Why are changes of state chemical changes?

They aren't; a change of state is a physical change


Are the changes in the state of matter chemical changes?

No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.


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.


Are state changes physical or chemical changes?

State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.


Are bateries chemical changes?

Yes. Chemical changes are changes in what things are made of, physical changes are changes of physical localization or state of matter ( liquid, solid, or gas)


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 phase changes physical or chemical?

Phase changes are physical changes, not chemical changes. They involve a change in the state of matter (solid, liquid, gas) without altering the chemical composition of the substance.


Are changes of state chemical or phisical?

both, but more physical than chemical


Is changing from a gas to a liquid a chemical change?

No, changes of state such as this are physical changes.


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.


Which occurs more often on earth physical changes or chemical changes?

Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.


Is melting snow a physical change or chemical change?

Snow disappearing is a physical change. It is a combination of melting and then evaporating and of sublimation.
