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.
How a thermometer can be callibrated?
A thermometer can be calibrated by placing it in a temperature-controlled environment, such as an ice bath or boiling water, and adjusting the reading to match the known temperature. This process ensures the accuracy of the thermometer readings and allows for corrections to be made if there are any discrepancies. Calibration should be done regularly to maintain the reliability of the thermometer.
why is it always the bulb of the thermometer that breaks?
The bulb of a thermometer is usually made of glass to allow for expansion and contraction of the liquid inside. When the thermometer is subject to sudden changes in temperature, the glass can crack or shatter due to thermal stress, causing the bulb to break.
What is the little hole on the thermometer?
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.
Why is the walls of long tube above the thermometer bulb are made thick?
The walls of the long tube above the thermometer bulb are made thick to provide insulation and minimize heat transfer from the environment, ensuring that the temperature measurement at the bulb is accurate and not influenced by external temperature changes. Thicker walls also help protect the thermometer from physical damage.
When did Galileo make the thermometer?
Galileo made the thermometer in 1593.
Why are the numbers where they are on a thermometer?
The numbers are where they are because the person who made the thermometer scale decided which numbers go where.
What is the raw experimental measurement made when using mercury thermometer?
Using a thermometer we can measure the temperature.

Is a thermometer made of the mercury element?
Yes
Who is Theodore hannes benzinger?
he made the ear thermometer
When the thermometer was first made?
it is a thing designed Arctic are
Was the thermometer invented on purpose or by accident?
no it was not made by accident. it was made by daniel gabriel fahrenheit. he wanted to make something to measure how hot or cold it is in a specific area. that is how the thermometer was invented.
What material is the tip of a oral digital thermometer made of?
Plastic
What is the year the thermometer was made by Galileo?
Galileo Galilei did not invent the thermometer. The first modern thermometer, using mercury in a glass tube, was invented by Daniel Gabriel Fahrenheit in the early 18th century, around 1714.
Who was the first person to make the thermometer in 1593?
The first person credited with inventing the thermometer in 1593 was Galileo Galilei, an Italian scientist and astronomer. He developed a device called the thermoscope, which later evolved into the modern thermometer.
