A student mixes salt, iron filings, and water. What happens to the physical properties of each material when it is mixed? How could the student separate the iron and salt from the water?
The salt dissolves, the iron filings sink, and you can use a magnet to remove the iron and evaporation to get the salt.
The salt floats, the iron filings dissolve, and you can use a filter to separate them.
The salt and iron filings both dissolve, and you can use a spoon to remove them.
The salt and iron filings both float, and you can use a net to separate them.
