AY Honors/Weather - Advanced/Answer Key

The maximum thermometer of the Six's thermometer is made of mercury and a metal index floating on top. When temperature rises,the mercury expands and the index is pushed upwards. When the temperature falls, the mercury contracts and the mercury level falls but the index stays in its position.

The minimum thermometer of the Six's thermometer is made of alcohol and a metal index. When the temperature cools, the alcohol drags down the index where it remains,eventhough the temperature rises.

A magnet is used to reset the thermometers and reset the metal indicators
