Answers
What is the use of maximum thermometer?
It is used to measure the maximum temperature within a period (usually daily). The most common maximum thermometer is the mercury-in-glass thermometer with a constriction in the bore below the lowest graduation. When temperature rises, the expansion force pushes the mercury through the constriction.
What is the use of minimum thermometer?
A thermometer that records the lowest temperature to which it has been exposed (e.g. by allowing a fall of mercury past a restriction in the tube, but preventing the mercury's return on expansion). It is most commonly used to record minimum daily temperatures.
Six's Maximum and Minimum thermometer is a U shaped parallel tube made up of glass. ... The bend at the bottom of the thermometer contains mercury which moves up or down based on the expansion and contraction of alcohol. When the temperature rises, the alcohol expands and pushes the mercury up the maximum column.
