What is a glass bulb of a thermometer?
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
What is a thermometer base called?
The base of a thermometer is called the bulb. It is typically a small, glass reservoir at the bottom of the thermometer where the liquid or mercury expands and contracts with changes in temperature.
How can I reset a Galileo thermometer?
To reset a Galileo thermometer, gently shake it or rotate it until all the glass bulbs are at the bottom. This will recalibrate the thermometer and allow it to accurately display the temperature.
How do you tell how hot or cold something is?
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.
Who inveted thermoeter first?
The first crude thermometer was invented by Galileo Galilei in the early 17th century. However, the modern thermometer, with a standardized scale, was developed by Gabriel Fahrenheit in the early 18th century.
What is the red dot at the bottom of a thermometer called?
thermometer is filed with mercury--HG
Why was it important not to let the thermometer rest on the bottom of the breaker?
It is important not to let the thermometer rest on the bottom of the beaker because the bottom can be heated unevenly leading to inaccurate temperature readings. Placing the thermometer in the liquid away from the bottom ensures a more accurate measurement of the liquid's temperature.
What is a glass bulb of a thermometer?
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
What is thermometer clamp?
The clamp holds the thermometer up right at the right hight. the bottom of the thermometer shouldn't be touching the bottom of the beaker or what ever it is. make sure the clamp his holding the very top of the thermometer so you can see the numbers.
What is a thermometer base called?
The base of a thermometer is called the bulb. It is typically a small, glass reservoir at the bottom of the thermometer where the liquid or mercury expands and contracts with changes in temperature.

Is the red dot at the bottom of a thermometer dangerous?
no I don't think so.
Where is most of the liquid in a thermometer?
Most of the liquid in a thermometer is typically found in the bulb at the bottom of the thermometer. This is where the temperature changes cause the liquid to expand or contract, moving up or down the tube to indicate the temperature.
What kind of thermometer is used for oral?
An oral thermometer is used for in the mouth and usually under the tongue. A rectal thermometer is used for taking your temperature from your rectum/bottom. They will be label in your grocery store or pharmacy whether there intended for your mouth or rectum.
What to use to measure the temperature of boiling water?
You can use a food thermometer or a candy thermometer for measuring the temperature of boiling water. Make sure the thermometer is heat-resistant and can handle high temperatures. Insert the thermometer into the water without touching the bottom of the pot for an accurate reading.
