PROJECT TITLE:

Cloud in a Bottle

Aim:

The purpose of this project is to show clouds form when invisible water vapor in the air is cooled to form tiny droplets of liquid water. In the atmosphere, when moist air cools as it rises to higher altitudes. At higher altitudes the pressure is lower, the gas expands, loses internal energy, and cools. You can accomplish the same cooling effect by rapidly expanding the air in a jar.
