Question

Question 5 5 pts the density of The molecular weight of water in comparison to that of oxygen and nitrogen moist air versus that of completely dry air. O lowers raises

Answer 1

Answer:

lowers

Explanation:

Moist air have lesser density than the dry air , since ,  

water has an atomic mass of 18

and diatomic molecule of oxygen , the atomic mass = 32 ,

and diatomic molecule of nitrogen , the atomic mass = 28 .

There fore , considering at constant temperature , the more water vapor that displaces the other gases , the less dense the air will be .

Hence ,  

The correct option is ' lowers ' .
