Question

write about theses scales :-

1) centigrade scale
2) Fahrenheit scale
3) kelvin scale
4) Rankine scale
5) Reaumur scale​

Answer 1

1. Centigrade scale (°C) - In this scale ice point and steam point are taken as 0°C and 100°C. 1°C is equal to 100 parts of difference between two points.

2. Fahrenheit scale (°F) - In this scale ice point and steam point are taken as 32°F and 212°F. 1°F is eual to the 180th part of difference between two points.

3. Kelvin scale (K) - In this scale ice point and steam point are taken as 273 K and 373 K. 1 K is equal to 100th part of difference between two points.

4. Rankine scale (°Ra) - In this scale ice point and steam point are taken as 460°Ra and 672°Ra. 1°Ra is equal to the 212th part of difference between two point.

5. Reaumur scale (°R) - In this scale ice point and steam point are taken as 0°R and 80°R . 1°R is equal to the 80th part of difference between two point.
