sand because when u see in microscope its a little hard shells
When water is mixed with salt, the properties of the salt remain unchanged. However, the properties of the water may change, such as its boiling and freezing points. The salt dissolves in the water, forming a homogeneous solution.
'Sand is mixed with salt' is a physical change because it involves a combination of two substances without altering their chemical identities. The individual particles of sand and salt retain their properties and can be separated by physical means, such as dissolving the salt in water or using filtration. No new substances are formed during this process, which is a key characteristic of physical changes.
No, a reaction with many substances is not a physical property of water. Physical properties of water include its boiling point, density, and color, whereas the ability to undergo reactions with different substances is a chemical property.
A purely physical association of substances refers to a mixture where the components are physically combined but retain their individual properties. This type of association can be separated through physical processes like filtration or evaporation, without changing the chemical makeup of the substances. Examples include salt dissolved in water or sand mixed with iron filings.
When two substances are mixed together physically with no chemical reaction taking place, it is called a physical mixture. The substances retain their individual properties and can be separated by physical means such as filtration or evaporation. Examples include mixing salt and pepper or oil and water.

because it is reversible and no new substances are formed
just the color

Mixing mud, sugar, and water is a physical change because there is no new substance formed. The individual components retain their chemical properties even after mixing.

you don't make any new substances, the sugar is just mixed very well into the water
Not all substances behave the same way when mixed with water. Some substances dissolve in water to form a solution, while others may react with water to form new compounds or stay separate as a suspension or colloid. The behavior of a substance in water depends on its chemical properties and the interactions between its molecules and water molecules.
No, sand does not dissolve in water, even if you stir it. Instead, when mixed with water, sand remains a separate solid particle that can settle at the bottom or remain suspended depending on the agitation. Unlike substances that dissolve, sand retains its physical properties and does not form a solution with water.
