Is dissolving sodium chloride a chemical or physical change?
The dissolution of sodium chloride is considered as a physical process.
Are all physical changes reversible with examples?
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
Is ductility a physical or a chemical change?
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.
When the physical form of substance changes without changing its composition?
This process is known as a physical change. It involves a change in the state or appearance of a substance but does not result in the formation of a new substance. Examples of physical changes include melting ice, boiling water, and breaking a glass bottle. The chemical composition of the substance remains the same throughout the physical change.
Why are most physical change easy to see?
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.

How can you tell that melting boiling dissolving are physical changes?
The physical and chemical properties, and chemical composition, are not changed after a physical change.
Is water condensing a chemical change?
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.

What happens when matter is changed physically?
It means that although it changes, no new substances are formed. Examples of such changes are melting and other state changes, and dissolving.
Physical changes that start with X and Y?

Explain why dissolving is a physical change?
All physical changes are reversible because the molecules do not undergo change in any chemical reaction even in in the change in the state of matter. NaCl is a salt compound and each molecules gets easily dissolved in water and the salt recovered by evaporation of water.
What are some physical examples?
physical examples are examples of thing or changes or transformations which you can see with you eyes or hold with your hands.
