Correct Answer: Temperature

Solution : The correct answer is Temperature .

The Reaumur scale, also referred to as the "octogesimal division", is a temperature scale that establishes 0° and 80° Celsius as the melting and boiling points of water, respectively. The physicist Rene Reaumur, who invented the scale in 1731, is honoured by the scale's name. The scale's unit of measurement is called Reaumur, or simply "Re". The melting point of ice and the boiling point of water, both at normal pressure, serve as the scale's two base points.
