The triple point of water is represented by which temperature?
A273.16 K
B173.16 K
C373.16 K
D573.16 K
Answer & Solution
Correct answer: A. 273.16 K
1. At the triple point all three states coexist.
2. That point fixes one end of the absolute temperature scale.
3. The triple point of water is represented by the temperature 273.16 K.
4. The pressure there is 6.11 times ten to the minus three pascal.
