Yes, this process is reversible; the water can be removed by evaporation or freeze drying.
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.
This is a reversible process.
Sifting!!!
Two common separating techniques used in the production of rice are threshing and winnowing. Threshing involves mechanically or manually separating the rice grains from the stalks and husks. Winnowing follows this process, where the lighter chaff is removed from the heavier rice grains by using wind or air currents to separate the two. These methods ensure that the rice is clean and ready for milling.

Reversible
It is reversible. You can allow the water to evaporate, leaving the salt behind.

It’s reversible
Freezing water is reversible because you can get it back to its original state by melting it - it turns back into water.
It is reversible because you can boil away the water and it will leave behind the sugar.
