Which statement is true about the temperature and density of air

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

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

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.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.
