Sublimation

An instructor was taking a ground school class for private pilots.

During the session on weather, the instructor wanted to discuss the concept of sublimation, the act of going from a gas to a solid skipping the intermediate liquid stage. He gave as an example water vapor in the air condensing on a windshield to form ice.

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. He was expecting “dry ice” as the answer.

One of the students blurted out, “Burritos.”
