Why does air pressure decreases when volume increases?
Air pressure is the weight of all the air above you. The higher you go, the more air is below you.
What is the upward force exerted by a fluid on a submerged object?
the weight water displaced (volume of the object times 62.4 for fresh water) minus the weight of the object in air
What is volume per unit weight?
Density is mass per unit volume, and sometimes in some industries weight per unit volume is used. Weight per unit volume is also sometimes called specific weight. Weight and mass are not the same. Volume per unit mass is called specific volume, and is the reciprocal of density. It is not clear whether volume per unit weight can also be used as a measure of specific volume.
What air force makes a air balloon go up and down?
This is the buoyancy force. Archimedes is credited with first formulating this into a mathematical principle: the buoyancy force of an object is equal to the weight of fluid it displaces. In the case of a hot air balloon, the "fluid" is the outside cool air and the balloon is displacing a volume of cool air equal to the volume of the inflated balloon. So you can say the buoyancy force F = V ρ g, where V is the volume of the inflated ballon, ρ is the outside air density, and g is gravity. A balloon can float because it is displacing this cool air with hot air which is less dense. The volume of hot air inside the balloon thus weighs less than the same volume of cold air outside the balloon. For a balloon to be float upwards, the buoyancy force has to be at least equal to the weight of the balloon (the balloon fabric, the gondola, the people, equipment and cargo, and the hot air inside). For example, for a balloon of 100,000 cubic foot volume (typical), with outside air at 20 deg C near sea level, the buoyancy force is about 7500 lbs. This force has to lift the gondola, people, equipment and of course the hot air inside the balloon, all of which have weight. By far the greatest percentage of that total weight is the heated air inside since there is so much of it.
How much weight will one liter of air float in water?
Disregarding the weight of the balloon or pontoon that holds the air . . .1 cubic foot (1,728 cubic inches, 7.481 gallons) for each 62.4 pounds of weight.Note: If the weight is hanging in the water, underthe air, then the weight itself produces somebuoyancy, and less air is required to keep it from sinking to the bottom. The amount of buoyancydepends on the volume of the weighty object, which can't be determined from the informationgiven in the question. (i.e., none)
What has no shape or volume it has weight but you cannot see it?
Air.
How much does a 10 pound brick weigh underwater?
That depends on the volume of the brick. Whatever its volume is, its weight underwater is(weight of the brick in air) minus (weight of an equal volume of water)
What does CWT mean in logistics?
Hi , CWT means chargeable weight of the shipment. There are 2 kind of weight in Air mode shipment - gross weight ie the actual weight of the shipment and volume weight , which is calculated based on the dimension. Airline charge freight based on the gross weight or volume weight which ever is higher. This is known as chargeable weight or CWT
What weight and volume of carbon dioxide would be produced by burning 24 grams of carbon in air?
Weight:1.45 grams volume: 6.789
What are the properties of air for kids?
There are various properties of air. Some of them are air has weight, air is under pressure, air has temperature, and air has a volume.
Is weight influenced by the force of volume?
No. Not at all. Volume has no force. Put 1 cubic foot of air inside a sealed jar, and weigh the air. Now let the same air into a 10-cubic-foot jar; seal the jar, and weigh the air again. The air has 10 times the original volume, but it still has exactly the same weight.
How do you you find volume from weight?
Weight doesn't tell you the volume. One pound of air, one pound of water, and one pound of gold all have vastly different volumes.
Why does air pressure decreases when volume increases?
Air pressure is the weight of all the air above you. The higher you go, the more air is below you.
What does 86 percent alcohol mean?
It means that either 86% of the weight is alcohol, or 86% of the volume. Volume is more standard, I believe.It means that either 86% of the weight is alcohol, or 86% of the volume.

What are the Characteristics of air?
Air has volume and weight but can be compressed. Air expands when it is heated and it keeps on moving from place to place depending on pressure.
What weighs 1 millilter?
Nothing does. A millilitre is a measure of volume, not weight. A millilitre of air will have a weight that is quite different from the weight of a millilitre of water or a millilitre of lead.
Propose a way to determine the density of air?
Get a vacuum chamber. Get all the air out of it, and weight it. This is the true weight of just the vacuum chamber. Fill it with air, and then weight it again. Subtract the new weight from the initial weight to get the mass of the air contained within the chamber. Find the volume of the chamber as well. density= mass/ voume. Hope it heelpss(:
