How does a glass thermometer works?
As the liquid in the thermometer is heated it expands, and the only way the expanding liquid can go is upward. As the liquid in the thermometer cools, it will contract, and the liquid will fall back down into the resevoir, causing the column of liquid to move downward.
Do pool thermometers contain mercury?
Most pool thermometers do not contain mercury. An easy way to tell if a pool thermometer contains mercury is if it sinks to the bottom of the pool rather than float.
How does a thermometer work as a tool to measure thermal energy?
The first units of heat (Fahrenheit and Celsius) were created based on the thermometer. Not the other way around. That way, the thermometer would always be accurate. The thermometer works by putting a specific amount of mercury (a strange metallic substance) inside a tube of a specific volume. When the thermometer is heated, the mercury expands, pushing itself up the tube. The mark that it reaches is measured and recorded in degrees.
Why are thermometer placed in armpit in getting body thermometer?

The most common and easiest way to measure thermal energy is with the use of a thermometer. The thermometer measures heat. Heat is the output of thermal energy.
What is the proper way to take the temperature of vacuum packed food?
The proper way to take the temperature of vacuum packed foods is with a metal stem thermometer. To take the correct temperature, put the thermometer in the center of the food.
What is the right way to measure the temperature of MAP or vacuum-packed foods?

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.
How do you measure room temperature using thermometer?
-- Bring thermometer into room. -- Wave it around in the air of the room for a minute or two. -- Do not hold the thermometer in your hand or breathe on it. -- Wait a while for the room temperature to get through the thermometer glass. -- Look through the glass at the sliver of liquid inside the thermometer. Find the end of the liquid, and see what number is marked on the glass at the same level. That number is your room temperature.

What are the stems of wine glasses for?
Some people think that the taste of the wine gets harmed by holding the bowl of the glass directly with the hand, so the stem keeps that body heat away from the wine. Actually, wine glass shapes come down through history as glass replicas of ancient brass goblets. These had very large bowls, difficult to hold in one hand, so the stem made it easier to handle. As glassware improved, the look stayed the same, although much smaller. So the real answer is that we like the way stemware looks.
What is the most appropriate way to hold a small wineglass?
Place the stem of the wine glass in between your index finger and your thumb. Then allow the rest of your fingers to hang down the stem!

It is not. Different people have different preferences for the way in which they can take in data. I'll take a well designed table over a stem and leaf any day.
Does a mercury thermometer provide info in an analog or digital way?
Analog way. Unless you have a digital thermometer
What is a thin glass tube with a bulb on one end that usually contains a liquid usually mercury or colored alcohol?
This could describe a thermometer. The only thing missing is the graduations. That way the height of the column can be associated with a specific temperature, the one that caused the column to be as high as it is.
How would you differentiate a tumbler from a footed glass?
A tumbler glass is shaped so that the base of the glass is also the bottom of its inside. A footed glass, on the other hand, is connected to a base by way of a stem. The length and width of the stem do not matter.
