Answer 1

Ways to Separate the Given Mixture:

To separate the given mixture, there are several methods that can be used depending on the specific components of the mixture. Here are the methods that can be used for each given mixture:

1. Oil and sawdust: One way to separate oil and sawdust is through filtration. Filtration involves passing the mixture through a filter, which allows the liquid (oil) to pass through while retaining the solid particles (sawdust) [[1]].

2. Sugar and water: The mixture of sugar and water can be separated through evaporation. By heating the mixture, the water will evaporate, leaving behind the sugar [[2]].

3. Gravel and sand: To separate gravel and sand, a method called sieving or screening can be used. Sieving involves passing the mixture through a sieve or screen with different-sized holes. The larger particles (gravel) will be retained on top of the sieve, while the smaller particles (sand) will pass through the holes [[3]].

4. Iron filings and sawdust: The mixture of iron filings and sawdust can be separated using a magnet. Since iron is magnetic, a magnet can be used to attract and separate the iron filings from the sawdust [[4]].

5. Chalk, salt, and water: The mixture of chalk, salt, and water can be separated through evaporation. By heating the mixture, the water will evaporate, leaving behind the chalk and salt. The chalk and salt can then be further separated using other methods, such as filtration to separate the chalk from the salt [[5]].

6. Sand, water, and salt: To separate sand, water, and salt, a combination of methods can be used. First, filtration can be used to separate the sand from the water. Then, evaporation can be used to separate the salt from the water. By heating the mixture, the water will evaporate, leaving behind the salt [[6]].

These methods are commonly used in laboratories and industries to separate different components of mixtures. Each method is selected based on the properties of the components and the desired outcome of the separation process.
