Question

Which statement is true about the temperature and density of air

Answer 1

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:

$PM=dRT$ ( from ideal equation)

P = pressure of the gas

M = Molar mass of the gas

R = Universal gas constant

T = Temperature of the gas

$\frac{PM}{TR}=d$

As we can see from the equation, that density is inversely proportional to the temperature of the gas.

$d\propto \frac{1}{T}$

This mean that at lower temperature gas will be more denser and at higher temperature gas will be less denser.

Answer 2

Answer:

lower temperature air more dense
