Why does the mercury fall or rise in a clinical thermometer when it is taken out of the mouth?
A clinical thermometer measures the max temp of the human body due to the expansion of the mercury in the bulb, which flows past a kink in the column and rises in the graduated stem, to read the highest body-temp. Once it is removed from the body, the mercury stays at that level, and does not fall because it cannot flow back into the bulb -- the kink prevents the back flow. It has to be shaken vigorously, as you know, for us to get the mercury back; then it is ready to take the temp again.. Also, the temp cannot rise further on its own from the max reading because the mercury does not expand the moment the thermometer is taken out of the body. Incidentally, temp can be measured under the armpits and in the rectum also.
Why does the mercury in the thermometer go up when the temperature is high?
In a mercury thermometer, the mercury expands when it is heated, causing it to rise in the thermometer's narrow tube. This increase in volume is a physical property of mercury known as thermal expansion. The height of the mercury column in the thermometer is then used to measure the temperature.
Why mercury used in minimum thermometer?
Mercury is used in minimum thermometers because it has a low freezing point (-38.8°C) and a high coefficient of expansion, making it sensitive to small temperature changes. This allows the thermometer to accurately measure and record the lowest temperature reached during a specific period.
What is the application of a Six's thermometer?
A Six's thermometer is typically used in meteorology to measure the minimum and maximum temperatures over a period of time. It consists of two mercury columns that are moved by the mercury in the thermometer to indicate the highest and lowest temperatures reached.
How does a minimum thermometer works?
A minimum thermometer works by using a small column of mercury or alcohol that moves up as temperature increases and down as temperature decreases. A small steel index marker within the column remains at the lowest temperature reached, allowing users to see and record the minimum temperature.
