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:
[tex]PM=dRT[/tex] ( from ideal equation)
P = pressure of the gas
M = Molar mass of the gas
R = Universal gas constant
T = Temperature of the gas
[tex]\frac{PM}{TR}=d[/tex]
As we can see from the equation, that density is inversely proportional to the temperature of the gas.
[tex]d\propto \frac{1}{T}[/tex]
This mean that at lower temperature gas will be more denser and at higher temperature gas will be less denser.
