Yes, sand and water can be separated through a physical process called filtration, making it a reversible change. By passing the mixture through a filter, the sand particles are retained while the water passes through, effectively separating the two components.
yes, just evaporate water and you are left with sand
Yes, mixing iron fillings with sand is a physical change. This is because no new substances are formed during the mixing process; the iron fillings and sand retain their original properties and can be separated back into their individual components.

Mixing is a physical change.
because it is reversible and no new substances are formed
Chemical
Yes, sieving sand from stones is reversible because the process can be undone by mixing the sand and stones back together. This separation technique relies on differences in particle size, making it easy to separate and recombine the materials as needed.
yes, just evaporate water and you are left with sand
The sand will simply go to the bottom of the container of water. Water and sand do not mix.
Yes, mixing iron fillings with sand is a physical change. This is because no new substances are formed during the mixing process; the iron fillings and sand retain their original properties and can be separated back into their individual components.
Mixing sodium chloride and water is a physical change. The chemical composition of the sodium chloride (NaCl) remains the same in the solution, the sodium chloride molecules are simply dispersed in the water. The change is reversible and does not involve a chemical reaction.
