How are physical and chemical changes distinguished?
Physical changes involve a change in appearance or state of matter without altering the composition, like melting ice. Chemical changes, on the other hand, result in the formation of new substances with different properties, such as rusting of iron. The key difference is that chemical changes involve breaking and forming of chemical bonds.
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.
What is the differnce between physical and chemical change?
Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.
What is changes of chemistry?
Changes in chemistry refer to alterations in the properties and composition of substances as a result of chemical reactions. These changes can be classified as physical changes, where the substance's form is altered without changing its composition, or chemical changes, where new substances are formed. Understanding these changes is fundamental to understanding the behavior of matter in various environments.

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.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
What is a key feature of a chemical change?
A key feature of a chemical change is the formation of new substances with different chemical properties from the original substances. This often involves the breaking and forming of chemical bonds.
do oreos undertake any chemical changes?
Do Oreos undertake any chemical changes? Yes. How can Oreo be a chemical changes? Cooking involve chemical reactions, modifications of chemical molecules.
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.
Changes in properties of matter are called?
physical or chemical changes
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
What is the process in which substances undergo chemical changes called?
chemical changes
What can chemical changes change?
Cooking food can cause chemical Changes
What is the key words of homeostasis?
Key words of homeostasis include balance, stability, regulation, and equilibrium. Homeostasis refers to the body's ability to maintain a stable internal environment despite external changes, through various physiological processes and feedback mechanisms.
If a new substance is produced is it a chemical change?
Correct; a chemical change produces a new substance, or in other words, an existing substance changes into a different substance.
