The little hole in a thermometer is called a "calibration port." It allows for adjustments to be made to the device to ensure its accuracy by verifying and potentially recalibrating the temperature readings.
To measure body temperature accurately, place the thermometer under the tongue, in the armpit, or rectally. Follow the manufacturer's instructions for the specific thermometer you are using.
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
The little lines on a thermometer typically count by 1 degree Fahrenheit or Celsius, depending on the scale used. Each line represents a small increment of temperature measurement.
A so-called "glass" thermometer has a small bore-hole in the center of the glass that has some liquid in it. It's the activity of the liquid in the narrow hole that makes the thermometer a thermometer.
The Mercury expands with temperature. Since expansion is linear over the normal range of a mercury-driven thermometer, the level of mercury within a little glass tube indicates the current temperature of the thermometer's immediate environment.

A regular candy thermometer can be used to measure the temperature of chocolate. The truth is you would be better off using a chocolate thermometer because it may be a little more accurate.

A calorimeter is used to keep heat contained in a single place as the calorimeter absorbs very little heat and the amount it absorbs can easily be calculated. To use the calorimeter heat the liquid you want (or cool) and place it in the calorimeter cup and put that in the calorimeter and place the lid on top and the thermometer in the thermometer's hole. There you go. Simple as that. A calorimeter is used to keep heat contained in a single place as the calorimeter absorbs very little heat and the amount it absorbs can easily be calculated.

Very simple answer: to make a hole in a cork or plastic stopper; the scope is to insert a tube, thermocouple, thermometer, etc.
Celsius, Fahrenheit, and Kelvin.

you blow at a diagnal into the hole at the top make a little hole with ur mouth and blow hard
