Hello friends
free point for everyone
Just joking
Here is my question and pls answer if u
Name the different type of scale used to measure temperature and also write their UPPER & LOWER fixed point
also mention all the formula to change one scale to another scale
kirtiprasanjenpchfhd:
3 types of scales are there
degree celcius(°C),fahrenite(F) and kelvin(K)

Temperature scales provide a way of quantifying and measuring how hot or cold a material is. There are four major temperature scales that are used around the world – Fahrenheit and Celsius are frequently used in everyday, around the house measurements, while the absolute zero-based Kelvin and Rankine scales are more commonly used in industry and the sciences.
1)FAHRENHEIT SCALE-Water freezes at 32 degrees Fahrenheit, and boils at 212 degrees F. The Fahrenheit temperature scale includes negative temperatures, below 0 degrees F. The coldest possible temperature, absolute zero, is -459.67 degrees F.
2)CELSIUS SCALE-water freezes at 0 degrees Celsius and boils at 100 degrees C. Because of how the boiling and freezing points are arranged, each degree of Fahrenheit is 1.8 times the size of a degree Celsius. Like Fahrenheit, Celsius includes negative temperatures. Absolute zero falls at -273.15 degrees C.
3)KELVIN SCALE-You can convert from Celsius to Kelvin by adding 273.15 to a Celsius temperature. Water freezes at 273.15 K, and boils at 373.15 K. Because of its direct relation to absolute zero, Kelvin temperature is widely used in scientific equations and calculations. For instance, the ideal gas law, used to show the relationship between mass, pressure, temperature and volume, uses Kelvin as its standard unit.
4)RANKINE SCALE-Temperatures can be converted from Fahrenheit to Rankine by adding 459.67. Absolute zero is thus located at 0 degrees Rankine. Water freezes at 491.67 degrees R, and boils at 671.67 degrees R.

Celsius scale :
The Celsius scale, previously known as the centigrade scale, is a temperature scale used by the International system of units..SI..
upper fixed point is 100℃
lower fixed point is 0℃
Fahrenheit scale :The Fahrenheit scale is a temperature scale based on one proposed in 1724 by Dutch–German–Polish physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit.
Lower fixed point is 32
upper fixed point is 212
