The question is incomplete, complete question is;
Which statement is true about the temperature and density of air
A. less dense air has a higher temperature .
B. very dense air has a very high temperature .
C. you cannot determine anything about density from temperature .
D. the more air there is, the lower the temperature and density
Answer:
The correct answer is option A.
Explanation:
The equation used:
( from ideal equation)
P = pressure of the gas
M = Molar mass of the gas
R = Universal gas constant
T = Temperature of the gas
![\frac{PM}{TR}=d](https://tex.z-dn.net/?f=%5Cfrac%7BPM%7D%7BTR%7D%3Dd)
As we can see from the equation, that density is inversely proportional to the temperature of the gas.
![d\propto \frac{1}{T}](https://tex.z-dn.net/?f=d%5Cpropto%20%5Cfrac%7B1%7D%7BT%7D)
This mean that at lower temperature gas will be more denser and at higher temperature gas will be less denser.
