Final answer:
The question is about the creation of a new temperature scale with temperatures given in m∘, but the Celsius and Fahrenheit scales are the most commonly used temperature scales with standardized freezing and boiling points for water.
Step-by-step explanation:
The question is related to the creation of a new temperature scale with temperatures given in m∘. In this proposed scale, 0.0∘m represents the normal melting point of mercury and 100.0∘m represents the normal boiling point of mercury.
However, it's important to note that the Celsius and Fahrenheit scales are the most commonly used temperature scales. On the Celsius scale, 0 °C is defined as the freezing point of water and 100 °C as the boiling point of water. Similarly, on the Fahrenheit scale, the freezing point of water is defined as 32 °F and the boiling point as 212 °F.
Therefore, while the idea of a new temperature scale using m∘ is interesting, the Celsius and Fahrenheit scales are widely used and have standardized freezing and boiling points for water.
