What is temperature facts for kids?
Useful temperatures Water freezes at a temperature of 0°C, 32°F, or 273.15 K. The temperature inside the human body is close to 37°C or 98°F. Water boils at 100°C, 212°F, or 373.15 K. The coldest possible temperature is absolute zero.
Who invented the thermometer?
The more modern thermometer was invented in 1709 by Daniel Fahrenheit. It was an enclosed glass tube that had a numerical scale, called the Fahrenheit scale. The early version of this thermometer contained alcohol and in 1714 Fahrenheit developed a mercury thermometer using the same scale.
How old is a thermometer?
English physician Sir Thomas Allbutt (1836–1925) invented the first practical medical thermometer used for taking the temperature of a person in 1867. It was portable, 6 inches in length, and able to record a patient’s temperature in 5 minutes.
Where was the thermometer invented?
The first recorded thermometer was produced by the Italian Santorio Santorio (1561-1636) who was one of a group of Venetian scientists working at the end of the 16th century. As with many inventions, the thermometer came about through the work of many scientists and was improved upon by many others.
What is a thermometer used for?
A thermometer is a device used for measuring temperature. This ice-covered thermometer shows that the temperature is about 0 degrees Celsius, or 32 degrees Fahrenheit.
How many types of thermometer are there?
Here, we will discuss the two types of thermometers, namely, clinical thermometer and laboratory thermometer.
What is thermometer short answer?
A thermometer is a tool that measures temperature — how hot or cold something is. Thermometers are used to see if you have a fever or tell you how cold it is outside. Made up of thermo (heat) and meter (measuring device), the meaning of the word thermometer is pretty straightforward.

What are some interesting facts about thermometers?
Interesting Thermometer Facts: A thermometer measures how cold or hot something is. The simplest thermometers are glass tubes that contain a liquid, usually mercury or alcohol, which expands with hat or contracts with cold. Many thermometers have both Celsius and Fahrenheit scales for reading the temperature.
What does a thermometer do?
A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object).
What is in a thermometer?
A thermometer is a device that measures temperature or a temperature gradient. A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature;
What is the temperature of a thermometer?
An instrument used to measure temperature (how hot or cold a thing is), usually in the Celsius or Fahrenheit scale . This thermometer shows a temperature of 28 degrees Celsius (which is about 82 degrees Fahrenheit)
