Why do objects weigh more in vacuum than in air?
Weight is dependant upon gravity and the relationship to large bodies of mass such as planets. However, if you were to be put into a vacuum on the surface of the Earth, you would way less. There is air pressure pushing down on you and that would add some weight. It also pushes up on parts of you. The difference is not likely to be very significant, but it should be measurable. However, I don't volunteer to be the person in the vacuum chamber! I am not a scientist, but I believe that you would weigh very slightly more in a vacuum. Think of our atmosphere as being a liquid of very low density compared with water. An object that floats in water displaces water in the amount of the object's weight; if you put a scale under a floating object, the scale registers the object's weight as zero. A perfectly bouyant object has the same density (specific gravity) as water, and as such will have a substantial weight if measured on land. But it will have no weight if weighed in water. An object that sinks in water will have weight, but it will weigh its land weight minus the weight of water displaced by its volume. This should be the same for a person (in a pressure suit, of course). The person will not be bouyed up at all by the atmosphere.
What are things that will sink in water?
weights, rocks, EARRINGS, fabric, broken boats, computers, houses... Anything that has a surface area, which displaces less water than the mass of the object, will sink. For example, water can support a 1 cubic foot object up 62.4lbs (in freshwater). If the object weighs more than that, but keeps the same dimensions, the water can no longer support it and that object will sink. If the object remains at 62.4lbs, but becomes less than 1 cubic foot, the object will sink, because it is displacing less water.
How much water is produced while burning one gallon of gasoline?
Burning 1 gallon of gasoline produces 1.52 gallons of water. How this is calculated:1 gallon of gasoline weights 8.66lbs, of which 1.4 lbs is Hydrogen, as gasoline contains 16% Hydrogen and 84% carbon by weight.This assumes gasoline has the chemical formula of C8H18, the same as Octane.Water is 11% Hydrogen and 89% Oxygen by weight. One gallon of water weights 8.35lbs, and contains .92 lbs of Hydrogen, and 7.43 lbs of oxygen.Therefore since hydrogen burned or in, equals hydrogen out after combustion, therefore 1.4 lbs of hydrogen burned, equals 1.4 lbs of hydrogen in the H20 or water created in combustion. By weight, 1.4 lbs of hydrogen divided by the weight of .92 lbs of hydrogen in water, equals 1.52. So 1.4 lbs of hydrogen in 1 gallon of gasoline, is converted to more gallons of water because gasoline contains more hydrogen per gallon, then does water.
How do you figure the buoyant force on an object in water in newtons?
Buoyancy = weight of displaced fluid. 10 newtons = 9.8 kilograms with 1G of force applied in a vacuum.
What happens to the mass of an object in water?
Mass is a measure of the amount of stuff of which a person or a thing is made. There's no reason the environment should have any effect on that amount. The object's mass doesn't change, whether it's in air, vacuum, maple syrup, or water, unless or until a piece falls off.
Can a hydrogen filled balloon float in vacuum?
no it will not. because a balloon filled with hydrogen floats only because it is lighter than air so when there is a vacuum it will not float. it is like oil and water if there is no water oil is on the bottom if there is water it is on the top.
What do you call the object that keeps water hot for hours?
Thermos flask or vacuum flask.
Which ketones are most soluble in water?
The ketones with lower molecular weights, are more soluble in water. The open oxygen can function as a hydrogen bond receptor.
How do you use pool cleaner weights?
Follow the directions for hooking up the vacuum either the one that uses the skimmer or the one that hooks up to a garden hose. Make sure all air is out of the hose and you have a good suction. Keep the vacuum head in the water. Then vacuum just like you would vacuum a carpet or floor.
What object does light travel through more slowly a vacuum water or glass?
Light travels very slowly in glass compared to water and vacuum
How many kg of water there is in a mol?
Water has two hydrogen atoms, and one oxygen atom. Look up their atomic weights, add them all up, and you will get the number of grams per mol.
What happen if I have an airtight object with air inside, it is rigid and also has the same density as water. now i submerge the object under the water, and then take the air out of it generating a vacuum, Would the object sink or would it stay in place?
sink

Can you get water from hydrogen?
You can get water from hydrogen if you combine the hydrogen with oxygen atoms.
What are characteristics of hydrogen?
Hydrogen is water...which can also produce electricity by the water wheel....Basically hydrogen is water..Theres nothing difficult about WATER/HYDROGEN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What kind of smoke is given when burning an object?
The kind of smoke from a burning object depends on the object itself. The common smoke that is given off is Hydrogen, Carbon Dioxide, Carbon Monoxide, and small amounts of Water Vapor.
