Question 1 of 10
Which statement is true about the temperature and density of air?
A. Lower temperature air is less dense.
B. The temperature and density of air are not related.
OC. Lower temperature air is more dense.
OD. The less air there is, the higher the temperature and density.

Answer 1

Lower temperature air is less dense.

Step-by-step explanation:

The correct statement about the temperature and density of air is option A: Lower temperature air is less dense. As temperature decreases, the air molecules lose kinetic energy and move slower, causing them to be closer together. This results in a decrease in volume but the same mass, leading to an increase in density.
