9. The no. of devisions between U.F.P and L.F.P on Fahrenheit scale is​

1. Upper fixed point is the boiling point of pure water at normal atmospheric pressure.

2. Lower fixed point is the melting point of pure ice at normal atmospheric pressure[tex].[/tex]

We know that,

• Normal atmospheric pressure = 1 atm

❖ Fahrenheit scale :

⟩ UFP = 212 °F

⟩ LFP = 32 °F

⟩ No. of divisions = 212 – 32 = 180

❖ Celsius scale :

⟩ UFP = 100 °C

⟩ LFP = 0 °C

⟩ No. of divisions = 100 – 0 = 100

❖ Kelvin scale :

⟩ UFP = 373 K

⟩ LFP = 273 K

⟩ No. of divisions = 373 – 273 = 100
