Question

Quizplus · Accepted Answer

A thermometer with a small constriction just above the bulb is a maximum thermometer, sometimes also called a self-registering thermometer. This type of thermometer works using a small column of mercury that is pushed along by the expanding liquid as it warms up. When the temperature decreases, the mercury column remains stationary at the point of maximum temperature, giving a reading of the highest temperature that was reached.
