Introduction
Separation of air.
Pre-Requisites:
Basic knowledge on Boiling points.
Activity:
Write down the order of any 5 gases when we see from top, knowing their BPs.
Real Life Question:
How do we get pure oxygen tanks in hospitals?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| distillation | A method of separation liquids with different Boiling Points |
| Boiling point | A temperature at which the liquid transforms to vapor state. |
| Fractional distillation | A method of separation of liquids with different BP’s, difference between BP <25C |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| BP chart | Understand the BP of gases and relation between which gets evaporated first. |
Real life uses :
Separation of air.
Practical examples around us
| Examples | Explainations |
|---|---|
| How do we get pure oxygen? | In the fractional distillation tower, the gases are separated in order of BP. At certain height gas will be pure oxygen. |
