Why does a nurse taking your temperature wait for the mercury thread in the thermometer to stop varying before taking the reading?
A nurse waits for the Mercury thread in the thermometer to stop varying because it ensures that an accurate and stable temperature reading is obtained. The mercury needs to settle to provide an exact measurement reflecting the patient's body temperature. Any movement can lead to an inaccurate reading.

What is the boiling point of the thermometer?
The question to ask is: What is the boiling point of mercury (as mercury is the substance within a thermometer, unless of course you are referring to the material that makes up the thermometer itself).You can simply google that.But...it's 356.7° C
Why can't you put a thermometer in a bowl of slurry ice?
Putting a thermometer into a bowl of slurry ice is a common method of calibrating it. It should read 0C or 32F. However, if the range of the thermometer does not include 0C or 32F, then this method of calibration won't work, so don't try to use it in that case.
What is a range of a gas thermometer?
The range of a gas thermometer depends on the type of gas used. Typically, gas thermometers can measure temperatures from -200°C to 600°C using various gases like nitrogen, hydrogen, or helium. Gas thermometers have a wide range compared to other types of thermometers due to the varying pressure-temperature relationships of different gases.
Proper Steps for Calibrating your Thermostat?
The varying temperatures found within the summer and winter seasons will have you adjusting the thermostat multiple times through the day. There may be, however, more money being spent in the heating and cooling of your house then actually needed. This extra cost may be caused by inaccurate readings coming off of your thermostat due to bad calibrations. Here are a few steps that can be run through to check and modify the calibrations of your home thermostat. •The first step would be to head down to the local hardware store or drug store to purchase a glass thermometer that uses mercury for readings. This thermometer will be set as close as possible to the thermostat using some sort of adhesive, such as tape or glue. •Once the thermometer has been in place for a few days to adapt to the air and temperature of the home, compare the readings on the thermometer with the readings of the thermostat at one hour intervals. If the temperatures are off by more than five degrees, it may be necessary to re-calibrate your thermostat. •Remove the cover of the thermostat and clean the area using an air cleaner normally used for keyboards and computer equipment. Once that dirt has been properly removed, use a paper towel that is a little damp to clean all of the components within the device. •The next step would be to un-screw the screws holding the thermostat to the wall and then removing it completely from where it is currently housed. There will be wires coming from the wall in a very small opening. The readings being wrong may be caused by the opening being larger than needed and causing air to effect the readings. This area around the wires can be plugged accordingly using a caulking compound and a painter’s stick. •The thermostat can then be reattached with the screws and adjusted so that everything is perfectly straight up and down on the wall. Once the cover has been reattached, the same procedures as before with the glass thermometer should be followed to obtain an accurate reading. •If the readings are still not up to standard, a new thermostat would have to be purchased and installed within your home.
What kind of instruments can you use to measure temperature?
You can use thermometers, thermocouples, infrared thermometers, and thermal cameras to measure temperature. These instruments can provide accurate readings of temperature in different environments and with varying levels of precision.
How did the thermometer make life better?
yes, indeed thermometer makes life better. if there was no thermometer people would not know about the temperature varying in their body and if they had fever they would not be able to know and cure it. hen of course it would lead to deaths.therefore without thermometer there would have been thousands of deaths. there are different types of thermometer not only for body temperature but also for the surroundings.

Who invented the thermometer in 1596?
Several inventors invented a version of the thermoscope at the same time. In 1593, Galileo Galilei invented a rudimentary water thermoscope, which for the first time, allowed temperature variations to be measured. Today, Galileo's inventioni is called the Galileo Thermometer, even though by definition it was really a thermoscope. It was a container filled with bulbs of varying mass, each with a temperature marking, the buoyancy of water changes with temperature, some of the bulbs sink while others float, the lowest bulb indicated what temperature it was. In 1612, the Italian inventor Santorio Santorio became the first inventor to put a numerical scale on his thermoscope. It was perhaps the first crude clinical thermometer, as it was designed to be place in a patient's mouth for temperature taking. Both Galilei's and Santorio's instruments were not very accurate. In 1654, the first enclosed liquid-in-a-glass thermometer was invented by the Grand Duke of Tuscany, Ferdinand II. The Duke used alcohol as his liquid. However, it was still inaccurate and used no standardized scale.Fahrenheit Scale - Daniel Gabriel FahrenheitWhat can be considered the first modern thermometer, the mercury thermometer with a standardized scale, was invented by Daniel Gabriel Fahrenheit in 1714. Daniel Gabriel Fahrenheit was the German physicist who invented a alcohol thermometer in 1709, and the mercury thermometer in 1714. In 1724, he introduced the standard temperature scale that bears his name - Fahrenheit Scale - that was used to record changes in temperature in an accurate fashion.
Can you control inside temperature of bulb when it is glowing.?
I hope temp inside the bulb can be control by varying the input voltage and monitoring it be Infra red thermometer. But it may possible that illumination of bulb get affected.
How does the Galileo thermometer work?
there are little glass bubbles filled with a colored liquid, usually food coloring and water oe coloured ethenol. each little bubble has a weight attached with the temperature engraved into it. all these bubbles are about the same density as water, and as the temperature changes, the bubbles float and sink. the bubble that sinks to the bottom is the current temperature.
What planet has the wildest swings in temperature?
Mercury has the wildest swings in temperature, with the surface temperature varying from about 800 degrees Fahrenheit during the day to around -290 degrees Fahrenheit at night due to its lack of atmosphere to retain heat.
What are the materials used for a Galileo thermometer?
A Galileo thermometer is a thermometer made of a sealed glass cylinder containing a clear liquid and a series of objects whose densities are such that they rise or fall as the temperature changes.

Varying cause wind?
temperature or magnitude
How does a car outside thermometer compensate for different air flows at varying speeds?
They don't, there usually in a sheltered position so there is no airflow.
Is this true . a given mineral can have varying densitys?
not at the same temperature
