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.
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.
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.
Where is it possible to learn about chemical changes?
Chemical changes can be learnt by studying the subject or by asking the state chemists. If you don't have time to visit the state chemists, then you can find the information on many websites.

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)
What is needed for a solid to sublime and what changes of state occur?
pressure and the change of state is chemical
Is decaying a chemical or physical changes?
Better to state it a biochemical change if required can state it chemical change
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.

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.
What are the differences between physical and chemical changes?
Physical changes involve a change in appearance or state of matter without altering the chemical composition, while chemical changes result in the formation of new substances with different chemical properties.
