Answer 2

Answer:

Fahrenheit scale is one of the three commonly used temperature scales (other two being Celsius and Kelvin scales). ... This scale was based on three fixed points. The lower fixed point of 32 degrees corresponded to freezing of water. The upper fixed point of 212 degrees corresponded to boiling of water.

Explanation:

Scales-

Celcius - °C = Upper fixed point = 100°C and lower fixed point = 0°C

Fahrenheit - °F = Upper fixed point = 212°F and lower fixed point = 32°F

Kelvin = K = Upper fixed point = 373K and lower fixed point = 273K
