Question

what is the 3 scales of temperature briefly explain

Answer 1

There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin.

Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts. The 18th-century German physicist Daniel Gabriel Fahrenheit originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of 30 and 90 for the freezing point of water and normal body temperature, respectively; these later were revised to 32 and 96, but the final scale required an adjustment to 98.6 for the latter value.

Celsius temperature scale also called centigrade temperature scale, is the scale based on 0 for the freezing point of water and 100 for the boiling point of water. Invented in 1742 by the Swedish astronomer Anders Celsius

Kelvin temperature scale is the base unit of thermodynamic temperature measurement in the International System (SI) of measurement. It is defined as 1/ 273.16 of the triple point (equilibrium among the solid, liquid, and gaseous phases) of pure water. The kelvin (symbol K without the degree sign []) is also the fundamental unit of the Kelvin scale

Answer 2

$\textbf{\underline{1.Centrigade\;Scale}}$

In this scale ice point is 0°C also Steam point is taken as 100°C.

In this scale 1°C = 100th part of difference between two points.

$\textbf{\underline{2.Fahrenheit\;Scale}}$

In this scale ice point is 32°F also Steam point is taken as 212°F.

In this scale 1°F = 180th part of difference between two points.

$\textbf{\underline{3.Kelvin\;Scale}}$

In this scale ice point is 273°K also Steam point is taken as 373°K.

In this scale 1°K = 100th part of difference between two points.

$\textbf{\underline{4.Rankine\;Scale}}$

In this scale ice point is 460°Ra also Steam point is taken as 672°Ra.

In this scale 1°Ra = 212th part of difference between two points.

$\textbf{\underline{5.Reaumur\;Scale}}$

In this scale ice point is 0°R also Steam point is taken as 80°R.

In this scale 1°R = 80th part of difference between two points.
