Which is an example of liquid glass thermometer?
Mercury Thermometers This type of thermometer was developed by a German based physicist named Daniel Gabriel Fahrenheit. It consists of mercury as a liquid filled in a glass tube. On the body of the glass tube, calibrated marks are provided which facilitates the reading of temperature.
How do I know if my glass thermometer is working?
(1) If the thermometer reading is below 94ºF (34.4º C), you have shaken down the thermometer sufficiently. (2) If the thermometer reads 94º F (34.4º C) or above, continue to shake down the thermometer until a desired reading is shown.
Can I use a mercury thermometer?
This thermometer is a thin glass tube with a silver tip and line inside. The silver tip and line is mercury. Mercury is a toxic and hazardous chemical.

A body temp between 100.4 and 102.2 degree is usually considered a low-grade fever. “If the temperature is not high, it doesn’t necessarily need to be treated with medication,” Dr. Joseph said.
Is 99 a fever in adults?
If you measured your temperature under your armpit, then 99°F or higher indicates a fever. Temperature measured rectally or in the ear is a fever at 100.4°F (38°C) or greater. An oral temperature of 100°F (37.8° C) or more is a fever.
Is 99 a fever forehead?
The following thermometer readings generally indicate a fever: Rectal, ear or temporal artery temperature of 100.4 (38 C) or higher. Oral temperature of 100 F (37.8 C) or higher. Armpit temperature of 99 F (37.2 C) or higher.
Which thermometer is best mercury or digital?
1. Digital thermometers provide faster results. Digital thermometers provide fast results as opposed to mercury thermometers whose readings are slower to realize because you have to wait for the mercury to heat and then slowly rise to display the temperature.
