A container contains a mixture of sand, salt, and pebbles. How can each substance be separated from the others?

1. Transfer the mixture to a water-filled container and thoroughly stir so that the salt dissolves.

2. Next, use a sieve to transfer the mixture (aqueous) into a different container so that the pebbles are separated out of the sand and solution.

3. Next, use a funnel with filter paper to transfer the salt solution containing sand into a different container, allowing the sand to be separated.

4. Lastly, take the leftover solution and heat it until the salt is still in the container and all the water has evaporated.

The sand, salt, and pebbles can be separated from each other through a combination of physical separation techniques such as filtration, evaporation, and sieving. Filtration can separate sand and pebbles from the salt solution, evaporation can separate the salt from the water, and sieving can separate the pebbles from the sand.
