### Object Weights more in air water vacuum or hydrogen?

ject weighs maximum in air ,hydrogen ,water, oil?

### 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.

### Does water affect the weight of an object the same thing as does submerging something in water affect the weight of an object?

Yes, when the object is submerged in water then water exerts opposite buoyonci force which decrease the weight of object.

### What happens when the water around objects have a force greater than the object's weight?

The water around floating object's is a measure of that object's "Displacement". For the object to float the weight of displacement must equal the object's weight. If the water around an object is of a greater weight than an object's displacement, then the object will sink.

### What is water buoyancY?

The difference between an object's weight, and the weight of water with the same volume as the object.

### What is Archimedes princible?

Archimedes principle states that : The force of buoyancy is equal to the weight of the displaced water. If the weight of the water displaced is less than the weight of the object , the object will sink. Otherwise the object will float , with the weight of the water displace equal to the weight of the object.

### What effect does buoyant force have on a submerged object?

The weight of the water displaced by the object is subtracted from the actual weight of the object (out of water), leaving the object with a net positive weight while submerged.

### What makes an object seem to weight less when you hold it in a pool of water?

This phenomenon is called buoyancy and is caused by the object displacing water equal to its volume. If the weight of the object is less than the weight of this displaced water, then the object has positive buoyancy and will float. If the weight of the object is exactly equal to the weight of this displaced water, then the object has neutral buoyancy and thus be weightless. If the weight of the object is greater than the weight of this displaced water, then the object has negative buoyancy and will sink but it still weighs less than it did out of the water.Just remember buoyancy only affects the weight of the object, it has no effect on the mass of the object which remains constant in or out of 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.

### Why the weight of object in water is less than in air?

The force of Buoyancy in water subtracts from the weight of the object in air.

### Why things sink into water any why not?

An object will sink if it has a greater density than water. In this case, the weight of the water displaced by the object is less than the weight of the object.

### Is a sphere of empty vacuum more buoyant in water than an equal size sphere of air?

When fully submerged on earth, yes. The net buoyancy force will be equal to the weight of the water displaced minus the weight of the object doing the displacing. Because the volume of water displaced by the water will be the same, and presumably have the same weight when the objects are both fully submerged, and the sphere of empty vacuum weighs less than the sphere of air, there will be a greater net upward buoyancy force on each object on earth.
