The temperature scale that sets freezing of pure water at 32o F:

Kelvin
Fahrenheit
Celsius
British

The correct answer is B. Fahrenheit.

The Fahrenheit scale is a temperature scale that was created by Daniel Gabriel Fahrenheit in 1724. It is the most common temperature scale in the United States and Canada, and is also used in some other countries, such as the Bahamas, Belize, the Cayman Islands, and Palau.

The Fahrenheit scale is based on the freezing point of water at 32 degrees Fahrenheit and the boiling point of water at 212 degrees Fahrenheit. The scale is divided into 180 degrees between these two points, with each degree representing a change of 1/180 of the total temperature range.

The Fahrenheit scale is named after its creator, Daniel Gabriel Fahrenheit. Fahrenheit was a German physicist and chemist who was born in Danzig (now Gdańsk, Poland) in 1686. He is best known for his work on temperature measurement, and for the development of the Fahrenheit temperature scale.

Fahrenheit died in 1736 at the age of 50. His temperature scale is still used today in many parts of the world.

The other options are incorrect.

  • Option A, Kelvin, is a temperature scale that is based on the absolute zero of temperature. Absolute zero is the temperature at which all molecular motion ceases. The Kelvin scale is used in science and engineering.
  • Option C, Celsius, is a temperature scale that is based on the freezing point of water at 0 degrees Celsius and the boiling point of water at 100 degrees Celsius. The Celsius scale is the most common temperature scale in Europe and most of the world.
  • Option D, British, is not a temperature scale.
