1. Greg tives by the sea and wants to make His own sen salt for cooking, Megets it from seawater.
2. Erle has made some brandy at home, He wants it to be stronger byremoving some of the water,
3. Boris accidentally drops thg of sugar in a bucket of hot water. Itdissolves, but he wants to get the solid sugar back
4. Lily is shipwrecked on an island. She needs clean water, but there isn'tany just a swamp with muddy water.
5. Angus has a bottle of alcohol mixed with water. He wants to remove thealcohol from the water to use as a fuel​

Answer 1

Different separation methods are best for each situation: evaporation for making sea salt from seawater, distillation to concentrate brandy and separate alcohol from water, crystallization to recover dissolved sugar, and filtration followed by distillation for purifying swamp water.

Step-by-step explanation:

In each of the described cases, different physical separation methods are used based on the mixtures and desired outcomes:

For Greg trying to make sea salt, the best method is evaporation. He can allow the seawater to evaporate, leaving the salt behind.Ernie who wishes to concentrate his brandy should use distillation. This process will remove some of the water, as alcohol has a lower boiling point than water.For Boris to recover sugar from the dissolved solution, crystallization could be used, where the water is slowly evaporated, leaving the sugar crystals behind.Lily stranded on an island needs clean water from swamp water. She should use filtration to remove larger impurities, followed by distillation to obtain pure water.Angus wants to separate alcohol from water for fuel. Distillation is the suitable method since alcohol has a lower boiling point, it will evaporate and condense first.
