Question

How do you measure temperature by using six’s maximum, minimum thermometer in your lab?

Answer 1

Answer:

Six's maximum and minimum thermometer is used for measuring the day's maximum and minimum temperature. It consists of a U-shaped capillary tube with bulbs at both ends. The bend of the U-tube is filled with mercury. One of the bulbs is completely filled with alcohol and the other bulb is partly filled with alcohol.

Answer 2

The maximum temperature in the Six's thermometer is recorded as follows.
Due to a rise in the temperature during the day, the alcohol in the completely-filled bulb expands and exerts a pressure on the mercury.
The mercury moves toward the partly-filled bulb and pushes up the index in the capillary closer to the partly-filled bulb. Thus, the index closer to the partly-filled bulb records the maximum temperature.

The minimum temperature in the Six's thermometer is recorded as follows.
Due to a fall in the temperature during the night, the alcohol in the completely-filled bulb contracts.
The mercury moves toward the completely-filled bulb and pushes up the index in the capillary closer to the completely-filled bulb. Thus, the index closer to the completely-filled bulb records the minimum temperature
