Mnemonic device for ideality of gases.

This mnemonic device is based on story method.

Nitrogen = Nitro = Car

Oxygen = Ox

Hydrogen = Hydrogen balloon

Carbon dioxide = white gas

ammonia = refrigerator = freeze

now the story begins.



Imagine there was a freeze in kitchen.

Then white gas was flowing out of that. White gas is carbon dioxide.

That you filled that on balloon and the balloon was used as fuel on ox.

The car was raced with that ox but cannot win that.a
