Why do you rotate the stem of the clinical thermometer when you read the thermometer?

If it is an analog thermometer, the face of the thermometer is shaped in a way that magnifies the readout, but it has a very narrow angle of visibility. Once rotated to the proper angle, the once thin line becomes a thick, easy to read line.

Why is the glass stem on a clinical thermometer designed to act like a magnifying glass?
The stem of the thermometer is not perfectly round for two reasons. One so it will not roll off and fall, and two, the flat area acts as a magnifying glass to make the hollow shaft in the stem appear larger.
Why is the stem of a thermometer designed like a magnifying glass?
So you can read it more easily.
Why is the stem of thermometer made up of glass?
To enable you to read the level the fluid has reached
Why does a stem in clinical thermometer have a small cross section area?
The small cross section of a clinical thermometer is there to reduce the amount needed of the toxic mercury to as little as possible. Mercury is less used nowadays, as breakages were likely due to the violent shaking needed to 'reset' the thermometer.
Why clinical thermometer often have oval stem in cross section?
Two advantage and two disadvantage of using alcohol and Mercury for thermome Two advantage and two disadvantage of using alcohol and Mercury for thermometer
What is the difference between a stem thermometer and a candy thermometer?
A stem thermometer is used to measure the internal temperatures of foods, especially meats. Stem thermometers have a "stem" that is inserted into the food and a flat round "face" at the top that may be digital or dail. Candy thermometers are used to measure the heat of candy while it is cooking. They are large straight tubes similar to thermometers used to take body temperature. They have a clip that enables the cook to clip it to the pan.
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.
What determines the range of a thermometer A. length of stem B. volume of bulb C. thickness of bulb D. volumn of stem?
None of the above
Is stem cell treatment legal in Australia?
Yes. Stem cell therapy is used to treat several conditions.There are currently many stem cell clinical trials underway in Australia.
Why does the substance in the thermometer stem rise up?
The substance in the thermometer (traditionally mercury (Hg)) rises up because of thermal expansion. As the substance heats up, it expands.
What do Hospital executives have to do with stem cells?
Hospital executives may engineer and structure research projects and clinical departments for the research and application of stem cells therapies.
What is a Bimetallic stemmed thermometer?
basically, a Bimetallic Stemmed thermometer is a thermometer that is used when cooking meats- like turkey (well turkey is poultry, but that is not the point) . They have a long stem that you poke into the meat and there is a dial on the top that tells you how hot the inside of the meat is.
