Who invented thermometer? The answer to this question is, who did we invent this post thermometer on our popular website today? Who invented and What is thermometer? Apart from this question, we will get many more information. Friends, keep reading this post and know who discovered the thermometer
The thermometer was invented in 1593 by Galileo Galilei. However the device he invented cannot be called a complete thermometer. Galileo's thermometer was only able to tell the temperature difference.
A person's temperature could not be measured by that. It can only be called a thermoscope that first tried to know the variation of water temperature.
Thermoscopes were old-fashioned thermometers with no scale to measure temperature. It was only able to tell the temperature difference. With the thermoscope, only the temperature between two objects is equal or lower or higher, could be measured.
In 1612, the Italian inventor Santorio Santorio (born 1561 – died 1636)) first applied a numerical scale on a thermoscope to make it used as a clinical thermometer. This thermoscope could be placed in the patient's mouth to measure temperature.
But neither the thermometer made by Galileo nor Santorio could make the correct measurements. Both had significant drawbacks in the thermometer.
1641 — Initiated closed thermometer — First built in 1641 by the Grand Duke of Tuscany, Ferdinand II (1610–1670), a fully closed and fluid-filled glass thermometer. His thermometer was filled with alcohol.
But even this thermometer was not useful in measuring one's temperature. However, it is considered an important discovery in the development of thermometers.
1714 – First Mercury thermometer: Daniel Gabriel Fahrenheit (1686–1736) was the first to use mercury (mercury) in thermometers.
The mercury filled thermometer that German physicist and a glassblower Fahrenheit built in 1714 can be said to be the predecessor of modern thermometers.
The nature of mercury changing with temperature has made it the most suitable material to be used in thermometers. Even today, we use only the thermometer of Mercury.
1724-FAHRENHEIT SCALE: Daniel Gabriel Fahrenheit
The Fahrenheit scale is considered an important discovery for measuring temperature. It was created in 1724 by a German physicist named Daniel Gabriel Fahrenheit.
To make this, Fahrenheit divided the points of freezing and boiling temperatures in water ice by 180 degrees. In his scale, he considered the freezing temperature of 32 degrees Fahrenheit because in his experiments he was able to achieve a minimum temperature of -32 degrees by mixing ice, water and salt.
Fahrenheit thus sets its measurement points based on human body temperature. Initially the human body temperature was 100 ° F on the Fahrenheit scale,
but it has since been fixed at 98.6 ° F. This scale has a boiling temperature of 212 ° F. Thus the temperature between freezing and boiling of water is divided into 180 degrees in the Fahrenheit scale. This scale is used in medical thermometers.
The Fahrenheit scale is used in medical thermometers. Health and normal humans have a body temperature of 98.6 degrees Fahrenheit.
1742-Centigrade Scale: Anders Celsius
The Celsius temperature scale is also known as the "centigrade" scale. It was invented in 1742 by the Swedish scientist Anders Celsius. This scale divides the freezing point (freezing point 0 ° C) and boiling temperature (100 ° C) at 100 ° at sea level pressure. The term "Celsius" (Celsius) was recognized for use internationally by the international conference on weights and measures held in 1948.
1848-Kelvin Scale: Lord Calvin
The temperatures that were measured in the Celsius and Fahrenheit scales were related only to the human body and water. But in the 19th century, scientists began to discover that what could be the lowest or lowest temperature in the world?
As a solution to this question, Lord Kelvin, with his invention of the Kelvin scale in 1848, stated that the lowest temperature, which he called the absolute zero or Absolute Zero, could be -273 ° C ° C. This -273 ° C temperature is called Absolute Zero which is assumed to be 0 ° Kelvin (0 Kelvin) in the scale they developed. Thus the extremes of hot and cold are measured in the Kelvin scale.
1867 - Also the first practical medical thermometer that can be used to take a person's temperature was made in 1867 by the English physician, Sir Thomas Elbatt (1836–1925).
A thermometer is a device that measures temperature. They use items that change their shape when the temperature changes.
For example mercury or mercury which is used in clinical or medical thermometers. The mercury size increases as the temperature rises, which can be measured after measuring.
