When the air rises does it increase or decrease?
When air rises, it expands and cools, which causes its density to decrease. Conversely, when air descends, it compresses and warms, which causes its density to increase.
What effect does air density have on the absorption and radiation of energy?
An increase in air density will mean a decrease in the absorption and radiation of energy. An increase of air density causes temperature and pressure to rise.
Why does density of air decrease with increase in height?
The density of air decreases with an increase in height due to the decrease in pressure and temperature with altitude. As you go higher in the atmosphere, there are fewer air molecules present, leading to lower air density.
Does air become lighter as the temperature rises?
noThe density decrease when the temperature increase.
Where is air density is greatest?
At the bottom of the troposphere
Why does a submarines density decrease when it pumps air out?
It doesn't pump air out; it forces water out of its ballast tanks to increase its buoyancy.
What two things affect density?
The two main factors that affect density are the mass of an object and its volume. An increase in mass or a decrease in volume will lead to an increase in density, whereas a decrease in mass or an increase in volume will result in a decrease in density.
What effects of increase does density do?
Density decrease when the temperature is raising.
Why the density of air decrease with the increase in height?
Because the higher you go, the less air there is above to push down and compress the air around you.
If you squeezed a balloon and made it smaller would the density in the air would become greater?
Yes. When you squeeze the balloon, you cause the volume to decrease. Since density is determined by dividing mass by volume, a decrease in volume will cause an increase in denisty.
Does evaporation of salt water cause it to increase or decrease density?
The density increase after evaporation.
How does a change volume affect an objects density when mass stays the same?
With constant mass, a decrease in volume will increase the the density. Conversely, an increase in volume will decrease the density.
