Physical changes can be temporary or permanent, depending on the nature of the change. Temporary changes, such as a sunburn or the effects of exercise, typically reverse over time. However, permanent physical changes, like scars or aging, may not revert back to their previous state.
Temporary changes to a material are known as physical changes. These changes do not alter the chemical composition of the material but only its physical properties such as shape, size, or state.
Temporary changes in materials are often referred to as physical changes. These changes do not alter the chemical composition of the material and can usually be reversed by physical means. Examples include changes in state (e.g. melting, freezing) or changes in shape.
Temporary changes to a material are referred to as "physical changes." These changes alter the state or appearance of a material without affecting its chemical composition, such as melting, freezing, or dissolving. Unlike chemical changes, physical changes are usually reversible.
Melting ice is a physical change because the properties of the physical changes say that there is a physical change when the state of a material changes. the ice changes into water after melting .this is temporary change as the property says. you can change water back into ice by freezing.
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.

A physical change is simply, a temporary change, which changes the physical characters of an object like its color, shape, size etc. It is a reversible change.
Matter can be changed through physical changes, such as melting or freezing, which are temporary and reversible. It can also undergo chemical changes, like burning or rusting, which are permanent and irreversible.

Physical Changes
In science change is nothing but the transfer of a matter or mixtures of matters from one state to another. Here the physical 'state' is not a matter, it may change or not. Permanent change of a matter is also a change of matter which wont regain its previous state. Burned paper is an example for permanent change and vapourisation of water is a temporary change. we can classify the changes(either physical or chemical) according to the changes whether it is permanent or temporary.

Migraines typically do not cause physical changes like a dent in the forehead. However, severe tension or muscle contractions associated with migraines can lead to temporary changes in the appearance of the forehead. If you notice a persistent dent or any unusual physical changes, it’s important to consult a healthcare professional for a proper evaluation.

There are no physical changes. there are only chemical changes.
