At the same pressure which is more more dense- hot air or cold air?

Cold air. At the same pressure, the VOLUME of a gas will be proportional to the absolute temperature - that is, to temperature expressed in Kelvin. Density is inversely proportional to volume.

∙ 7y agoThe absorbed energy makes the molecules in air move and expand, therefore decreasing the airs density. The opposite is true for cold air. It is more dense because the molecules are closer together and they are closer together because the bonds are absorbing less energy and therefore do not move as much.

What is the difference between cold and hot densities?
For the same substance, it will be less dense at higher temperatures and more dense at colder temperatures. There are a few exceptions, for instance water between 0 and 4 degrees C.
Why does a balloon deflate in cold air and expand in hot air?
Because the pressure of a gas is dependent on the temperature. The same amount of gas - as what you have inside your balloon - will have a higher pressure when it's warm, and a lower pressure when it's cold. And higher pressure = more inflation. Lower pressure = less inflation.
Is an ice cube more dense or less dense than liquid water?
Less dense. For most substances, the solid form is more dense than the liquid form; water is a notable exception.Less dense.

Is a cannon ball more or less dense than a water balloon the same size?
less dense
Where will you experience greater pressure swimming in the sea or in the pool at the same depth?
Salt water is more dense than fresh water. The added density adds pressure, so the pressure will be greater at the same depth in salt water. This is also the cause of the increase of buoyancy in saltwater.
Is cold air thicker or thinner than warm air?
Hot air hasLess atmospheric pressure, in other words the air is thinner. ... Cold air is heavier than hot air *at the same pressure*
Is water vapor more or less dense than dinitrogen under the same conditions of temperature and pressure?
less dense
Are helium balloons more dense than air baloons?
No. At the same pressure, a helium filled balloon will be less dense than an air-filled balloon.
Is cold air heavier than warm air?
False because warm air rises. The particles in cold air are moving more slowly and make cold air more dense than warm air.
Is hot water pressure and cold water pressure equal in pressure?
Pressure is the same whether hot or cold.
What is more dense one mL of water or fifty mL of water .?
If the conditions are the same [temperature, pressure, presence or absence of dissolved substances,...] then they have the same density.
Why does cold water in a tube sink to the bottom of room temperature water?
Cold water is dense and cold water sinks, just like air, cold air falls and hot air rises.
Why do balloons deflate in cold weather?
Because the pressure of a gas is dependent on the temperature. The same amount of gas - as what you have inside your balloon - will have a higher pressure when it's warm, and a lower pressure when it's cold. And higher pressure = more inflation. Lower pressure = less inflation.
What are the two factors that determine the movement of air mass?
Two main factors that influence air movement are pressure and temperature, though they are really the same thing. Air moves to places with less pressure, to "fill them up," and gets pushed away from areas with high pressure. Also, when air gets hot, it becomes less dense than the air around it and is pushed upward. When it gets cold, it becomes more dense, and sinks toward the ground.
Is Warm air is less dense than cold air?
No it's just less dense. For the same volume of air, warm air is lighter.
How much does air weigh when weighed in air?
Yes, it does. The air has air pressure all around you, about the weight of 2 elephants. Then you would ask, Why are we not we crushed? It is because You breathe in that air and you have the same air inside you that is outside.Yes.Air does have a weight, yes.
What is the difference between cold and hot densities?
