physical changes~ cutting of paper, parked car, melting butter, flat Basketball, and broken glass.
chemical changes~burning gas, reacting iron with sulfur, vaporizing water.

it is a chemical change because it causing the fuel to burn
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
Physical and chemical changes are harmful to us.
No, it is a Physical Change. Physical Changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (condensation, melting, freezing, vaporization, sublimation) are physical changes. Other examples of physical changes include crushing a can, melting ice, and breaking a bottle. Chemical changes take place on the molecular level. A Chemical Change produces a new substance. Some examples of chemical changes include combustion (burning) and rusting of a metal.
Chemical changes take place on the molecular level
There are no physical changes. there are only 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.
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 phase change is a physical change. It is not a chemical change.
No, physical changes involve a change in appearance, texture, or state of matter without altering the chemical composition of the substance. In contrast, chemical changes result in the formation of new substances with different chemical properties.
what involves both chemical and physical change on earths surface
Examples of physical changes include melting of ice, boiling of water, cutting a piece of paper, breaking a glass, and dissolving salt in water. These changes alter the form or appearance of a substance without changing its chemical composition.
Chemical and physical changes are part of methods applied in science.
chemical
physical changes do not change the chemical properties of a substance
yes it can be called physical and chemical reaction
