    The triple point of water               is

    A) \[273.16{}^\circ C\]

    B)                        \[273.16\text{ }K\]         

    C) \[273.16{}^\circ F\]         

    D)        \[0.15\text{ }K\]

    Correct Answer: B

    Solution :

    The triple point of water is the single combination of temperature and pressure at which liquid water, gasceres water and ice (solid water) coexist in equilibrium. This triple point occurs at a temperature of approximately \[0.01{{\,}^{o}}C\]and a pressure of 4.58 mm of mercury. On the scale, which use the unit kelvin, the temperature of water at the trpile point was set at 273.1-6 K, abbreviated as 273.16 K. Note: The absolute temperature scale, also called the kelvin scale, employs the SI unit of absolute temperature.
