One way we can separate a solution is through a process called distillation.
3
Let's take a look at this process in action.
4
Step 1.
5
Set up the distillation apparatus.
6
The typical distillation apparatus consists of a burner, a distillation flask containing the substance we want to distill,
7
a thermometer, a condenser, a receiving flask, and some corks to connect the components.
8
Step 2.
9
Cool the condenser.
10
Cool water is fed into and out of the condenser to keep it at a low temperature.
11
This is essential for condensing the vapour back into a liquid.
12
Step 3.
13
Heat the substance.
14
The burner is used to heat the substance we wish to distill in the distillation flask.
15
As the temperature rises, keep an eye on the thermometer to monitor the boiling point of the substance.
16
Step 4.
17
Vaporisation As the substance is heated, it begins to evaporate and boil,
18
causing vapour to rise from the liquid in the distillation flask.
19
Step 5.
20
Vapour enters the condenser The vapour passes through the neck of the distillation flask and enters the condenser.
21
The condenser is kept cool by the circulating water, which causes the vapour to cool and condense back into a liquid.
22
Step 6.
23
Collection of the distillate The condensed liquid,
24
known as the distillate, drips from the condenser into the receiving flask.
25
This distillate is the purified substance that we aimed to separate from the mixture in the distillation flask.
26
Step 7.
27
Completion of distillation
28
the distillation process continues until all of the desired substance has been vaporized
29
and condensed into the receiving flask the substance remaining in the distillation flask
30
which has a higher boiling point is called the residue
31
or the still bottom by carefully controlling the temperature
32
and collecting the distillate at the appropriate boiling point we can separate
33
and purify the desired substance from a mixture using the distillation apparatus.
34
This method is widely used for various purposes, such as purifying water, perfumery and the production of essential oils.

シャドーイングとは?英語上達に効果的な理由

シャドーイング(Shadowing)は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的:ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影(shadow)」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
