Introduction
• The ideal gas equation of state is not sufficient to describe the pressure, volume, and temperature behaviour of most real gases. • Most real gases do not show ideal behaviour at low temperature and high pressure.
Pre-Requisites:
Partial pressure, volume, gas, temperature,
Activity:
LPG gas in the cylinders and gases in the fire extinguishers are compressed liquefied gases.
Real Life Question:
How do gases become liquefied?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Boyle Point | The temperature at which a real gas obeys ideal gas law over a wide range of pressure. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Can of coke | If you heat up a can of coke on a flame. Be very careful and do not attempt it in the kitchen. |
Real life uses :
LPG gas for cooking.
Places to visit :
kitchen
Practical examples around us
| Examples | Explainations |
|---|---|
| Liquefied gases | Liquefied gases in the cylinder and fire extinguishers are used in every household. |
What you learn in Theory:
Real gases do not follow the assumptions of the kinetic molecular theory of gases at all conditions.
What you learn in Practice:
• Real molecules have volume. • There are intermolecular forces.
