Question

what is the triple point of water at 0.0 atm (atmospheres) of pressure? ____ °k

Explanation:

Step1: Recall triple - point definition

The triple - point of water is a well - defined physical property and occurs at a specific pressure and temperature. The triple - point of water is the temperature and pressure at which solid, liquid, and gaseous water co - exist in equilibrium. The pressure at the triple - point of water is 0.00603 atm and the temperature is 273.16 K. The given pressure of 0.0 atm is not the triple - point pressure. But the temperature of the triple - point of water is an absolute value and is 273.16 K regardless of the incorrect pressure value given in the non - standard context of the problem.

Answer:

273.16
