Question

To measure the minimum and maximum temperature in a day, which thermometer is used?
A. One’s thermometer
B. Clinical thermometer
C. Six’s thermometer
D. Long thermometer

Answer 1

Hint: It is an enrolling thermometer that can record the most extreme and least temperatures came to throughout some period, for instance, 24 hours. It is utilized to record the boundaries of temperature at an area, for example in meteorology and horticulture. It was imagined by a British researcher James Six, brought into the world in Canterbury, in 1780; a similar fundamental plan stays being used.

Complete answer:
To quantify the base and most extreme temperature in a day, Six's thermometer is utilized. It comprises a U-formed slim cylinder having bulbs at the two closures. Mercury is filled in the curve of the U-tube. One of the bulbs is loaded up with liquor and the other bulb is halfway loaded up with liquor. Liquor is the thermometric fluid in the event of Six's thermometer. Temperature change is recorded because of the development and constriction of liquor.
It is likewise generally known as a most extreme least, least great, maxima–minima or minima–maxima thermometer, of which it is the soonest pragmatic plan. The thermometer shows the current temperature and the most elevated and least temperatures since the last reset.
The thermometer comprises a U-molded glass tube with two separate temperature scales set along each arm of the U. One of these is for recording the greatest temperature experienced and the other for the base temperature. The arms of the U-molded cylinder end in fixed glass bulbs. The bulb at the highest point of the base perusing scale arm is brimming with liquor, while the other contains a vacuum (or low weight liquor fume).
In the twist of the U is a part of mercury, a metal that is fluid at ordinary temperatures. This is pushed around by the warm extension and withdrawal of the liquor in the principal bulb as it reacts to the outer temperature. The vacuum in the other bulb permits the free development of the liquor and mercury. It is the liquor that quantifies the temperature; the mercury shows the temperature perusing on the two scales. This is not normal for a typical mercury thermometer, in which the extension and constriction of mercury itself show temperature.

Thus, option (C) is correct.

Note: The most extreme and least readings are recorded by two little steel markers which are sprung into the slim cylinder so they can slide, however just if power is applied to them, either by being pushed by the mercury or affected by an outside magnet.
