<span>Compare Bromine and Krypton on the basis of their properties, attributes and periodic table facts. Compare elements on more than 90 properties. All the elements of similar categories show a lot of similarities and differences in their chemical, atomic, physical properties and uses. These similarities and dissimilarities should be known while we study periodic table elements. You can study the detailed comparison between Bromine vs Krypton with most reliable information about their properties, attributes, facts, uses etc.</span>
Answer: The boiling point of water at 81 kPa will be 298.17 K.
Explanation:
The boiling point of water is 373 K at atmospheric pressure. So, to calculate the boiling point at 81 kPa, we use the law given by Gay-Lussac.
Gay-Lussac Law states that pressure is directly proportional to the temperature when volume and moles remain constant.
Mathematically,

where,
= Initial pressure and temperature
= Final pressure and temperature
We are given:

Putting values in above equation, we get:

Hence, the boiling point of water at 81 kPa will be 298.17 K.
