Warm air has less pressure than cold air because it is less dense. As a gas is heated, its particles separate farther apart, making it less dense. Less dense gas creates less pressure.
That is incorrect. Think of a pressurized tank of air, cold it has 120psi as you heat the pressurized tank up the pressure increases. It is because the molecules when cold are tightly packed and not bumping into each other as much as when warm and moving around bumping into one another.
Air is heavier in warmer weather than in winter. This is because warm air is less dense than cold air, causing it to weigh more in the same volume compared to cold air.
No, warm air and cold air exert different pressures due to their different densities, but the weight of a volume of air is determined by its mass. Therefore, a mass of warm air does not weigh more than a mass of cold air, assuming the volumes are the same.
warm air is less dense than cold air due to the fact that the molecules in warm air have more energy and thus move farther apart from each other. This results in less mass per unit volume of warm air compared to cold air.
They weigh the same. Both are defined in your question as a pound.
Cold air is more dense than warm air. If flows beneath the warm air and forces it to rise.When air warms up, it expands a little, and so it becomes less dense. Density is the ratio of mass to volume. Within a fixed volume, there will be less mass (less air) in a sample of warmer air than there will be in a sample of cooler air. The less dense air floats above the cooler air. This is why hot air balloons will rise.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
True... warm water is less dense than cold water.
a little
Warm water is less dense than cold water, so it sits on top of the cold water. This is because warm water molecules are more spread out and have less mass per unit volume compared to cold water molecules, causing warm water to be less dense and float on top of the denser cold water.
Air is heavier in warmer weather than in winter. This is because warm air is less dense than cold air, causing it to weigh more in the same volume compared to cold air.
Cold air falls and warm air rises. Warmer air rises above cooler air because it is less dense. The particles vibrate and move further apart so the molecules that compose the air are more spread out, causing the warm air mass to weigh less than the cool air.ass
yes
it rises
Cold air is more dense than warm air.
no, warm air holds more water vapour than cold air
No, warm air and cold air exert different pressures due to their different densities, but the weight of a volume of air is determined by its mass. Therefore, a mass of warm air does not weigh more than a mass of cold air, assuming the volumes are the same.
No, warm air is less dense than cold air because the molecules in warm air have more energy and are spread out more, resulting in lower density.
