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.

Can warm air pressure weigh more than cold air pressure?
yes
What weighs less a pound of cold air or a pound of warm air?
They weigh the same. Both are defined in your question as a pound.
What causes the warm air ahead of a cold front to rise?
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.
Volume of warm air weighs less than an equal volume of cold air because?
It's less dense
Is cold air denser than normal air?
Yes, cold air does have a higher density than warm air. For example, if you turn on the fireplace, all of the warm air rises to the ceiling. On the floor, the air is cooler.
What is less dense warm air or cold air?
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
The density of warm water is less than that of cold water true or false?
True... warm water is less dense than cold water.
Cold air is than warm air?
Cold air is more dense and less buoyant than warm air.
How much more does warm air weigh than cold air?
a little
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
Can warm air pressure weigh more than cold air pressure?
yes
Can warm air hold less water vapor than cold air?
no, warm air holds more water vapour than cold air
Why does warm air weigh less than cool 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
Is warm air less dense than cold air?
yes
What is Warm air is less dense than cold air?
it rises
Why does warm water sit on top of cold water?
Warm water is less dense than cold water, hence, it floats on top.
What weighs less a pound of cold air or a pound of warm air?
They weigh the same. Both are defined in your question as a pound.
