Mercury thermometers maximum, how to operate
The ambient temperature is lower than body temperature, and the mercury itself should fall down. However, this does not happen because of a particular design. The tube through which the mercury creeping up, on the border with the bulb has curvature and narrowing. This is done to ensure that mercury remained in place, and the result was available to all.
You need to consider that the cost of mercury thermometer is much lower than electronic.
Otherwise, if the column is dropped, the exact temperature could not be seen, because once the column started to fall down. Under this option, the indicators will stray. And return the thermometer to a working state is possible only with sharp and repeated shaking. If on the scale of the mercury is 35 degrees and above, the device must be operational with shaking.
