Introduction
Discuss “How the PV Vs. P graph of different gases”
Pre-Requisites:
Matter, StoichiometryMatter, Stoichiometry
Activity:
Connect a syringe filled with air to a to a pressure gauge. You will observe that as you compress the volume the pressure will increase.
Real Life Question:
“How do gases behave at different temperatures?”
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Avogadro’s Hypothesis | For a gas, at a given volume, pressure and temperature the number of molecules is fixed |
| Ideal Gases | Gases that follow the ideal gas law (pV = nRT) |
| Partial Pressure | The pressure that would be exerted by one gas in a mixture of gas it is occupied by the same volume on is own. |
| Dalton’s Law of Partial Pressure | The total pressure exerted by a gas mixture is the sum of partial pressures of the gases in the mixture |
Learning aids / Gadgets
