What else can I help you with?
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.
Do warm air have weight?
Ofcourse it has weight, it's just lighter than cold air. With that, you can make hot air balloons, because the hot/warm air inside the balloon is lighter than the cold air outside the balloon. And ofcourse warm air does have weight, because it's made out of a lot of different gasses. It has to weigh something, because air contains gasses. if you make a square the size of 1 dm^2, and you imagine a collumn all the way from the square to the end of the earths atmospere, you wil get +- 1 kg of air.
Can warm air pressure weigh more than cold air pressure?
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.
What is draft in a boiler?
when the weight of warm air in the stack is less than the cool air around the stack , it causes an upward flow pulling air thru the furnace
What is draft in boiler?
when the weight of warm air in the stack is less than the cool air around the stack , it causes an upward flow pulling air thru the furnace
When warm air meets cool air does the warm air sink?
The cold air pushes under the warm air.
Does Cold Air Exerts More Pressure Than Warm Air?
In warm air, molecules are spaced farther apart. As air cools, molecular activity and movement slows down which cause compaction of the molecules. The increased density of air in the same space automatically increases the overall weight. That is why warmer air layers over cold air because the cold air is 'heavier' and sinks to the ground while the 'lighter', warm air rises.
Why does a down filled sleeping bag keep you warm?
Down traps a lot of air, and air is a good insulator.
When cold air moves toward warm air it pushes the warm air?
I pushes the warm air upwards.
Air warm rebus?
warm air
What air mass is warm?
a warm air mass is a large body of air that is extremely warm
What does warm air do?
Warm air rises,and then sinks when the air is cold.
