Registers maximum and minimum temperatures in both °C (range: −40 to 50° with 1° divisions) and °F (range: −40 to 120° with 2° divisions).
Beside this, how do you find the maximum temperature?
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.
Also, is mercury used in maximum minimum thermometer?
There are two liquids which are used in maximum and minimum thermometer. In the glass bulb ethanol is present and in the U shaped tube which connect the two bulbs Mercury is present.
What do you mean by minimum thermometer?
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.
What is maximum & minimum temperature?
MAXIMUM TEMPERATURE: The definition of maximum is the largest number or highest number of something that is permissible or possible. MINIMUM TEMPERATURE: The lowest temperature recorded—diurnally, monthly, seasonally, or annually, or the lowest temperature of the entire record.
What is maximum minimum thermometer in science?
a thermometer that records the highest and lowest temperatures since it was last set.
What is the difference between a maximum and a minimum thermometer?
1. The maximum thermometer is a thermometer that records the highest temperatures reached during a period of time, whereas The minimum thermometer is a thermometer that records the lowest temperature reached during a period of time.
What is the maximum temp?
As such, it seems that the highest possible known temperature is 142 nonillion kelvins (1032 K.). This is the highest temperature that we know of according to the standard model of particle physics, which is the physics that underlies and governs our universe. Beyond this, physics starts to breakdown.
What is the minimum temperature for fever?
Fever. In most adults, an oral or axillary temperature above 37.6°C (99.7°F) or a rectal or ear temperature above 38.1°C (100.6°F) is considered a fever. A child has a fever when his or her rectal temperature is higher than 38°C (100.4°F) or armpit (axillary) temperature is higher than 37.5°C (99.5°F).
Why alcohol is used in a minimum thermometer?
Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. … If it freezes it won’t move in the tube, so a liquid must be used that has a freezing point that’s lower than the temperature it’s measuring.
