Solution
To make tea, we will use the following steps:
- Take 100 mL of water, which will serve as the solvent.
- Boil water on a gas stove.
- Add one teaspoon of sugar, which acts as a solute.
- Sugar is soluble in water, therefore it dissolves in water and forms a solution.
- Now add roughly half a teaspoon of tea leaves that are insoluble in water.
- Boil the contents for 4 to 5 minutes, then add a half cup of milk and continue to boil for 2-3 minutes.
- Filter the tea using a sieve.
- Tea leaves will be left as residue, and tea will be extracted as filtrate.
