an increase in air temperature causes expansion of gas therefore a decrease in density. colder air is denser hence valley bottoms are often colder

When altitude increases does air density?
The density of the atmosphere decreases with altitude.
What effects on density of air if tempecture increase?
A gas (including air) will expand if the temperature increases. That means the same mass of gas will have a larger volume. Since density is mass / volume, that means the density will decrease.
What happens to air as temperature increases?
Air pressure rises and drops as the temperate changes because the higher temperatures weigh down the air to create low pressure. When it is cooler, the air can rise more which creates high pressure.
Taking heat out of the air will do what to the air temperature?
Removing heat from the air will lower its temperature.
In a temperature inversion air temperature does what?
increases with height
Is the density in warm air high or low?
As temperature increases, density decreases.
What factor will increase the speed of a sound wave in the air?
Speed of sound would increase as the temperature of the air increases Speed of sound increases as humidity of air increases Speed of sound is affected by the density of the air. As density increases velocity of sound decreases
What happens to the speed of sound if the temperature of the medium increases?
Speed of sound increase when temperature increases.
How are temperature and air mass related?
For a given volume and pressure, the mass of the air contained in that volume (density) will decrease as the temperature increases.
Why does temperature affect the air pressure?
Air temperature and air pressure are inversely proportional. As temperature increases, air pressure decreases. This is best demonstrated in an enclosed vessel.
What happens to the density of air as it's temperature increases?
Becomes lighter and rises, the principle of hot air balloons.
Does sound travel faster in hotter or colder temperatures?
The speed of sound in air increases with temperature, as the density of the air decreases.
When altitude increases does air density?
The density of the atmosphere decreases with altitude.
Does air temperature affect air resistance?
There are two factors that influence air resistance with temperature. Air density decreases with temperature so that the force needed to push the air out of the way is decreased, thereby decreasing resistance. Conversely, air viscosity increases with temperature (unlike oil for example where viscosity decreases with temperature) so that the drag increases. Under normal conditions, the density change of air has the greatest effect and air resistance decreases at higher temperatures.
What is the relationship between air temperature and its density?
air temperature: the temperature of the air... air density: how much air there is, for example on top of a mountain there is low air density because there is not much air but at sea level there is higher air density because there is lots of air. this happens becuse air actually has a mass and it sinks down to sea level where it cannot go lower. The density of all materials is dependent on ambient temperature. For gases the influence of temperature is stronger. Raising the temperature of a gas (air) the density is lower and inversely.
What effects air pressure and density?
Volume and Temperature. Higher temperature increases pressure and decreases density. Lower temperature decreases pressure and increases density. (Except with water, in which case ice is less dense than liquid water. [Keep in mind that vapor is still less dense than liquid and follows the rules.] This is the only exception known to me). Higher volume decreases pressure and increases density. Lower volume increases pressure and decreases density.
What effects on density of air if tempecture increase?
A gas (including air) will expand if the temperature increases. That means the same mass of gas will have a larger volume. Since density is mass / volume, that means the density will decrease.
