Question

What is the standard unit of measuring temperature?

Answer 1

Hint: The energy state of matter is described by temperature, which is an intensive quantity. Atoms and molecules in all materials are constantly moving, vibrating, or rotating. The more they move, the higher the temperature of the material. The average kinetic energy of an object's atoms and molecules can be used to determine its temperature, which is a simple definition for temperature.

Complete step by step answer:
The energy state of matter is defined by temperature. The average kinetic energy of an object's atoms and molecules can be used to determine its temperature.
-The SI system's base unit of temperature is Kelvin.
-The derived unit of temperature measurement is the degree Celsius.
-Temperature is measured in Celsius, Fahrenheit, Kelvin, and other units.
-A typical adult's body temperature ranges from 97 to 99 degrees Fahrenheit (37 degrees Celsius).

The relation between Celsius, Fahrenheit, and Kelvin is as follows:
Celsius to Kelvin
$K{=}^{0}C+273$
Celsius to Fahrenheit
${}^{0}C={\displaystyle \frac{{}^{0}F-32}{1.8}}$
The SI system's base unit of temperature is Kelvin (International System of Units). The abbreviation for the Kelvin unit is K. (no degree or degree sign). In 1848, William Thomson (Lord Kelvin) presented the Kelvin unit for the first time.

Celsius is currently a derived unit for temperature. Celsius is abbreviated as ${}^{0}C$ (degree Celsius), and one Celsius degree equals one kelvin degree. The freezing point of water (or melting point of ice) was defined as 0 degrees Celsius, while the boiling point of water was defined as 100 degrees Celsius.

The abbreviation for the Fahrenheit unit is ${}^{0}F$. Gabriel Fahrenheit, a Dutchman, was the first to introduce the Fahrenheit scale in 1724. The scale's two main reference points are the freezing point of water, which is 32°F, and the temperature of the human body, which is 96°F.

Note:The third law of thermodynamics states that no energy can be removed from matter as heat at absolute zero temperature. Although matter has no macroscopic thermal energy at this temperature, it does have quantum-mechanical zero-point energy, as predicted by the uncertainty principle, which is not included in the definition of absolute temperature.
