Are physical properties such as temperature invented or discovered?



Temperature itself was not invented. Even though there were no ways to calculate temperature during the earliest days of our planet, every area has, and always had a specific temperature. However, the methods we use to quantify temperature such as thermometers and scales were invented for our convenience.


Even though temperature was always there, it wasn’t until 1593 when Galileo invented the first rudimentary water thermometer to become the first person to put a number on temperature. In 1709, a “German physicist named Daniel Gabriel Fahrenheit invented the first alcohol thermometer and the first mercury thermometer in 1714.” (Mary Bellis) (Mercury thermometers are still prominent in today's society.) In 1724, the first temperature scale was named after its creator “The Fahrenheit Scale.”
The Celsius Scale was invented by a Swedish astronomer named Anders Celsius. “The Celsius scale is often times referred to as the centigrade scale which means consisting of or dividing by 100.” (Mary Bellis) The scale has 100 degrees between freezing point (0) and boiling point (100.) This scale was adopted in 1948 to be the international scale that is used for temperature.

These are two scales that were invented to calculate temperatures of water, of air, and of certain gases. The scales were created to quantify temperature, which was previously unable to be calculated for many millennia.

Everyday application of Hess's Law

  Everyday application of Hess's Law Burning calories, consuming food, driving home, we all should be familiar with these actions because we do them everyday, but what some of us don't realise is that all these actions related one fundamental law of conservation of energy, Hess's Law.   Hess's Law states that: regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes. [1]   We will further discover how our indrustries, human body and drug production are related to this law and to better understand the science behind it. Industries Today, all our mass and low cost production depends on factories and industries and all these industries require huge amount of energy.   To keep everything the most efficient possible, these industries has to determine the method that is the most effective to produce a product based on the energy needed or released.   For example:  Car companies must determine ho

Antoine Lavoisier and his contribution to Chemistry

The French Bourgeoisie helping out with science: “In performing experiments, it is necessary… that they be simplified as much as possible, and that every circumstance that could complicate the results should be completely removed.” -Antoine Lavoisier Early life and Work: On the 26 of  August 1743, Antoine Lavoisier was born to a wealthy family of nobility and was the son of an attorney at the Parliament of Paris. He  went to school at the College des Quatres Nations, University of Paris at the age of 11 were he studied chemistry, botany, astronomy and mathematics and received a law degree which admitted him the bar. (1). This French nobleman, chemist and biologist is credited for being the first one to put an extensive lists of the elements, helping construct the metric system and reform chemical nomenclature. Lavoisier is also known as the “ father of modern chemistry” (1). Lavoisier who was originally part of the Ferme generale ( most hated components of the F

TOK Blog Are physical properties such as temperature invented or discovered? Even tho we don’t know exactly how temperature was invented or discovered we know for sure the Galileo Galilei was the first human being that came up with the idea of an instrument able to calculate the temperature know as a thermometer. Many scientist don’t really recognize Galilei’s instrument as a thermometer but, more as thermoscope because his device only showed the change in temperature and had no scale .The measurement of temperature consist of “The process of measuring a current local temperature for immediate or later evaluation.” Celcius In 1742 two years before his death Celcius created a scale which was reversed a 0° represented the boiling point of water and 100° represented the freezing point of water. Kelvin In 1848, William Thomson created the Absolute Thermometric Scale that could measure the absolute zero as the scale's null point, and in which he used the Celsius as
