Detailed Solution

Concept: An international scale for measuring temperature, the Kelvin scale can convert between Fahrenheit and Celsius.
While the triple point of water remains constant at 273.16K, the boiling point of water and the melting point of ice can both change depending on the system's temperature and pressure.
While triple point is constant, the values of melting and boiling points can change depending on pressure and temperature.
The melting point of ice at atmospheric pressure is 0°C on the Celsius scale, and 273.15 K is the value for absolute temperature. The triple point of water is found at a temperature of 273.16 K.
Hence, option 1 is correct.
