To separate each mixture, different methods can be used depending on the specific mixture. Here is a breakdown of how to separate each mixture and the methods involved:
a) To separate sand and water, you can use the method of filtration. Take a filter or a piece of cloth and pour the mixture through it. The sand particles will be caught on the filter, while the water will pass through.
b) To separate oil and water, you can use the method of density. Oil is less dense than water, so it floats on the surface. By carefully pouring off the oil layer from the top, you can separate it from water.
c) To separate salt and pepper, you can use the method of picking apart. Manual separation is possible by carefully picking out the salt grains from the pepper particles.
d) To separate sand and pebbles, you can use the method of filtering. Similar to the sand and water mixture, you can pour the mixture through a filter or a piece of cloth. The sand particles will be caught in the filter, leaving the pebbles behind.
e) To separate sugar and water, you can use the method of dissolving and evaporation. By adding sugar to water and stirring, the sugar will dissolve in the water. Then, you can heat the solution to evaporate the water, leaving behind the sugar crystals.
Regarding the second question about filters in your home and school, it is unclear what specific filters are being referred to. Filters can serve various purposes, depending on their design and location. Here are a few examples of filters in different settings:
a) In a home, you might have a coffee filter or a water filter. The purpose of a coffee filter is to separate the ground coffee from the liquid coffee when preparing a cup of coffee. A water filter, on the other hand, removes impurities and contaminants from tap water, making it safe to drink.
b) In a school, there might be air filters in the HVAC systems. These filters are designed to remove dust, allergens, and other pollutants from the air, providing clean and healthy indoor air quality for students and staff.
c) It is unclear what filter is mentioned in option c.
d) In a school science laboratory, there might be filter papers that are used for various filtration processes during experiments. They allow the separation of solid impurities from liquids.
e) It is unclear what filter is mentioned in option e.
To provide a more accurate explanation, a specific filter would need to be mentioned or clarified in option c and e.
