A physical change is either a change of state (solid to liquid, liquid to gas, etc) or a change of shape (squeezing a piece of playdoh or plaster, screwing up a piece of paper).
A chemical change involves the production of a new substance, so it involves the rearranging of the atoms in molecules of a substance.
A physical change is relatively easy to reverse, a chemical change is hard or impossible to reverse. Signs a chemcial change has taken place include a permanent change of colour, bubbling meaning a gas has been produced, change of temperature, the appearance or disappearance of a material.
Examples of chemical change include burning toast, cooking an egg, setting concrete.
Physical changes involve a change in appearance or state of matter without altering the chemical composition of the substance. Chemical changes result in the formation of new substances with different chemical properties from the original materials. Physical changes are usually reversible, while chemical changes are often irreversible.

Changes in properties of matter are called?
physical or chemical changes.
What 2 things can chemical and physical change go through?
Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the appearance or state of matter without changing the chemical composition. Chemical changes typically involve the breaking and forming of chemical bonds, resulting in new substances with different properties. Physical changes, on the other hand, involve changes in physical characteristics such as shape, size, phase, or state of matter without altering the chemical composition of the substance.
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.
When an element transmutates the number of changes?
When an element transmutates, its number of protons change, which in turn changes its atomic number and chemical properties. These changes can result in the formation of a different element with different physical and chemical characteristics.
Is ability to react with other substances chemical or physical?
The ability for a substance to react with other substances is a chemical property, as it involves changes in the substance's chemical composition. Physical properties, on the other hand, relate to characteristics such as color, shape, and state of matter, which do not involve changes in chemical composition.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
Changes in properties of matter are called?
physical or chemical changes.
What is the differences between chemical and physical change?
A chemical change results in the formation of new substances with different properties, while a physical change alters the state or appearance of a substance without changing its chemical composition. Chemical changes involve the breaking and forming of chemical bonds, whereas physical changes involve changes in the physical state, such as melting, freezing, or evaporating.

Chemical changes typically involve the breaking and forming of chemical bonds, resulting in new substances with different properties. Physical changes, on the other hand, involve changes in physical characteristics such as shape, size, phase, or state of matter without altering the chemical composition of the substance.
Are state changes chemical or physical changes?
Physical Changes
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Is shortening melting a chemical property?
No, shortening melting is a physical property. Chemical properties involve changes in the chemical makeup of a substance, while physical properties describe characteristics that can be observed without changing the substance's chemical composition.
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.
When an element transmutates the number of changes?
When an element transmutates, its number of protons change, which in turn changes its atomic number and chemical properties. These changes can result in the formation of a different element with different physical and chemical characteristics.
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.
Is ability to react with other substances chemical or physical?
The ability for a substance to react with other substances is a chemical property, as it involves changes in the substance's chemical composition. Physical properties, on the other hand, relate to characteristics such as color, shape, and state of matter, which do not involve changes in chemical composition.
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.
