Question

What is the relationship between air temperature and density?

A. When air temperature is stable, it becomes more dense.
B. As air gets cooler, it becomes less dense.
C. As air gets warmer, it becomes less dense.
D. Air temperature cannot be used to predict air density.

Answer 1

The relationship between air temperature and density is that as air gets warmer, it becomes less dense, and as air gets cooler, it becomes more dense.

Step-by-step explanation:

The relationship between air temperature and density in physics is that as the air gets warmer, it becomes less dense while as air gets cooler, it becomes more dense. This is because as air is heated, its molecules gain energy and move faster, causing them to spread out and occupy a larger volume. Conversely, when air is cooled, its molecules lose energy and move slower, causing them to come closer together and occupy a smaller volume.

For example, if you compare a hot air balloon with a cold air balloon, the hot air balloon will be less dense because the air inside it is warmer, while the cold air balloon will be more dense because the air inside it is cooler.

Therefore, option C is the correct answer for the relationship between air temperature and density.
