What is the primary advantage of using the triple-point of water as a standard fixed point in modern thermometry over using the melting point of ice and the boiling point of water, as originally done in the Celsius scale?

Options

  1. AThe triple-point is more precise and reproducible.
  2. BThe Celsius scale has been updated to use the triple-point.
  3. CThe triple-point is easier to measure accurately.
  4. DThe melting point and boiling point are not well-defined.

Correct answer

A. The triple-point is more precise and reproducible.

Step-by-step solution

Correct Option is : (A) The triple-point is more precise and reproducible.
