Galileo Thermometer

A Galileo thermometer is based on the principles that the density of a fluid expands and contracts depending on temperature. The thermometer consists of a liquid in a seal cylinder with several calibrated liquid filled glass sphere fitted with differing metal weights. Since the spheres are of slightly different weights, as the temperature changes the spheres rise or fall in sequence according to their weight. If the temperate decreases the spheres rise. If it increases the sphere fall. The movement of the spheres is entirely dependent on the environmental changes and not because of any action of the spheres.

The Galileo Thermometer is an excellent example to show how as the environmental conditions change, objects move naturally according to the energy changes rather than by choice.
