Is it possible to use a smartphone as a thermometer?
Manufacturers of thermometers must demonstrate to the appropriate authorities that their instruments actually provide accurate and dependable readings, whereas manufacturers of smartphones do not. Making decisions based on erroneous body temperature data is risky and might be harmful to one’s health.
You use a thermometer, but why?
Measuring body temperature can aid in the diagnosis of disease. Additionally, it can track the effectiveness of treatment. A fever is a high temperature.
Why does a thermometer include mercury?
Mercury’s steady expansion upon heating, rather than its conductivity, is the reason we use it in thermometers. It has been chosen above other liquids because of its ideal rate of expansion, which allows us to use a calibrated thermometer to make measurements in a temperature range of interest.
A maximum-minimum thermometer: what is it?
A thermometer that is intended to document the highest and lowest temperatures that have transpired during a certain time frame. It typically consists of a graded capillary tube with an ethanol-containing bulb at its base. A tiny thread of mercury with a steel index at either end is found inside the capillary.
And how do thermometers function?
Typically, a thermometer consists of a tiny, hollow glass tube. A bulb at the tube’s bottom contains a liquid, such as alcohol or mercury. The liquid inside the bulb expands as the temperature rises, forcing upward into the tube. As the temperature drops, the liquid can compress and flow through the tube.
