10/17/07 Grif.Net – Sublimation

A friend wrote: “Some time ago, I was taking a ground school class for
private pilots. During the sessions on weather, the instructor wanted to
discuss the concept of sublimation – the act of going from a gas to a solid
skipping the intermediate stage(s). (e.g., frost – water vapor in the air
becoming a solid on surfaces without first going through the liquid stage.)

Wanting to see if the class had understood the concept, the instructor asked
if anyone could provide an example of something that went straight from a
solid to a gas (expecting ‘dry ice’ as the answer). A previously unknown
section of my mind took control of my mouth and immediately emitted the word
‘beans’.

It took the instructor about 10 minutes to regain an academic composure.”
