An object's weight in air is the same as its weight in a vacuum. This is because weight measures the force of gravity acting on an object, and gravity affects objects in air and in vacuum in the same way.

Does an object weigh more in water or in air?

An object will typically weigh less in water compared to in air, due to the buoyant force acting on it when submerged. This is because the water exerts an upward force on the object, partially offsetting its weight.


Does a balloon without air weigh the same filled with air?

No, a balloon without air would weigh less than a balloon filled with air. The weight of an object is determined by the mass of the object and without the air filling the balloon, there is less mass present, therefore less weight.


How much more does an object weigh after it has been submerged out of water?

Submerged "out-of-water". That is not possible. It is either submerged or it is out of water. Even when an object is submerger or partically submerged it will not weigh less. The physical characteristics (weight) of the object cannot be changed. The object, when placed in water will displace a certain amount of water and the object will float if the weight of the displaced water is more that the weight of the object. The object will then sink if it weighted more that the weight of the water it displaces. That said, the actual weight of the object doesnt change but if a scale were attached to it while hanging in air, it would read greater that when the object is floating or submerged in water.


When does an object with twice the mass of another weigh twice as much?

An object with twice the mass of another will weigh twice as much when both objects are on the same planet or celestial body with a constant gravitational acceleration. Weight is directly proportional to mass when the gravitational acceleration remains constant.


How much does sound weigh?

Sound in air is simply a compression of air at the frequency of the sound. The sound itself does not weigh anything, but the medium it is travelling in will have its own weight per unit volume.
