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.
Step-by-step 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
As we can see from the equation, that density is inversely proportional to the temperature of the gas.
This mean that at lower temperature gas will be more denser and at higher temperature gas will be less denser.
