aeriform

Warm dry air, especially when in motion, promotes the aeriform transpiration, by favouring evaporation.

When the principle of attraction prevails, it causes them to become solid; when caloric prevails, they become aeriform.

What is the cause of bodies being either solid, liquid, or aeriform?

Personally I prefer the aeriform fluid in front of the curtain.

Beside these gases, the air always contains a quantity of the vapor of water in a perfectly aeriform and transparent condition.
