A chemical change is a change involving making and breaking chemical bonds to form new chemicals. For example when wood burns the carbon and hydrogen in the cellulose react with the oxygen in the air, forming carbon dioxide and water. A physical change is one that the chemical changes states and no new chemicals are formed, like melting ice or dissolving salt in water.

What are some steps to physical and chemical change?

Physical change involves a change in the form or state of matter without changing its chemical composition, such as melting ice to water. Chemical change involves a change in the chemical composition of a substance, resulting in new products being formed, such as burning wood to produce ash and smoke. Observing changes in properties, such as color, odor, or temperature, can help distinguish between physical and chemical changes.


What is the diffrenece between a physical change and a chemical change?

Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.


How does a chemical differ from a physical change?

A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes

What methods do scientist use to determine if it is a physical or chemical change?

Scientists distinguish between physical and chemical changes by examining if the change affects the chemical composition of the substances involved. Physical changes alter the appearance or state of a substance without changing its chemical makeup, while chemical changes result in the formation of new substances with different chemical properties through chemical reactions. Techniques such as observing color changes, production of gas, formation of a precipitate, or changes in temperature can help scientists identify whether a physical or chemical change has occurred.

What criteria are used to distinguish between a chemical and physical change?

One distinguishing feature between physical and chemical changes is that a physical change can be reverse or turn back to its original form, but chemical change cannot be return to its form because the material change.


Difference between chemical and physical change?

A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
