Maximum and minimum temperatures are measured using thermometers mounted inside a wooden box with slits, called Stevenson’s screen, which is generally kept facing north. The maximum thermometer is mercury-in-glass — as the temperature rises, the mercury expands and moves freely up a constriction in the thermometer.
What is maximum thermometer used for?
maximum thermometer A thermometer that records the highest temperature to which it has been exposed (e.g. by allowing a rise of mercury past a restriction in the tube, but preventing the mercury’s return on contraction). It is most commonly used to record maximum daily temperatures.
How do you find the maximum temperature?
To measure the minimum and maximum temperature in a day, Six’s thermometer is used.It consists of a U-shaped capillary tube having bulbs at both ends. Mercury is filled in the bend of the U-tube. Alcohol is the thermometric liquid in case of Six’s thermometer.
What is the use of minimum thermometer?
a thermometer designed to show the lowest temperature recorded between resettings.
What are 3 types of thermometers?
There are different types, but not all thermometers are right for your child.
Digital thermometers. Ear (or tympanic) thermometers. Infared thermometers. Strip-type thermometers. Mercury thermometers.
Why alcohol is used in minimum thermometer?
Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. Pure ethanol freezes at -115 degrees C, while mercury freezes at -38 degrees C.
What do you mean by minimum and maximum temperature?
Minimum temperatures of an area or place is the lowest temperature at that place in a given time period. The lowest possible temperature is -273 degree Celsius, or 0 Kelvin( Kelvin is a unit of temperature) Maximum temperature is the highest temperature at a place in a given time period .
What is the difference between minimum and maximum temperature called?
The difference between the maximum and minimum temperature in a day is called the range of temperature.
What is minimum temperature for thermometer?
The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.
