Yes, a physical change is not permanent and can be reversed.
Yes, all substances can undergo physical changes. Physical changes do not alter the chemical composition of a substance, but rather change its physical properties such as shape, size, or state (solid, liquid, gas). Examples of physical changes include melting, freezing, boiling, or dissolving.
Being ductile, malleable, freezing, melting are some examples of physical changes of a substance. Physical changes do not form a new substance while chemical changes do. Examples of chemical changes are a rusting nail and combustion.
Physical transformation of matter refers to changes in the physical state or appearance of a substance without altering its chemical composition. Examples include changes in state (solid to liquid to gas), dissolving, melting, freezing, and evaporation. These transformations do not involve a change in the fundamental chemical makeup of the substance.
Sugar dissolving in water is a physical change where the sugar particles break apart and mix with water molecules, forming a homogeneous solution. Evaporation, on the other hand, is a process where liquid water changes into water vapor due to heat energy, breaking intermolecular forces. Both processes involve changes in the physical state or composition of substances without altering their chemical properties.
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
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.
All changes are usually easy to see. Physical changes are changes that do not make new substances, but still see a movement in the parts. Breaking a glass, melting an ice cube, boiling water, or dissolving salt are good examples.
Melting ice into water and breaking a glass bottle are examples of physical changes. These changes do not alter the chemical composition of the substances involved, only their physical state or appearance.
Mixing salt and sand together, dissolving sugar in water, and heating water to convert it to steam are all examples of physical changes, not chemical reactions.
Melting of ice, boiling of water, tearing a piece of paper, and breaking a glass are all examples of physical changes. These changes do not alter the chemical composition of the substances involved, they only involve a change in their physical appearance or state.

The physical and chemical properties, and chemical composition, are not changed after a physical change.
Physical changes do not alter the chemical composition of a substance, only its physical appearance or state. Examples include changes in shape, size, phase (solid, liquid, gas), or state of matter (melting, freezing, dissolving).
Physical changes are those changes which do not cause a change in the chemical composition of the changed body. For example, change in the state of matter of a body, change in state of rest or motion of the body.

The process in operation when rock is broken and disintegrated without dissolving is called mechanical weathering. This typically involves physical forces such as temperature changes, freeze-thaw cycles, or plant roots breaking the rock apart without changing its chemical composition.
