# Does water displacement theory apply to other liquids?

In summary, water displacement theory, also known as Archimedes' principle, states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid it displaces. This principle can be applied to any liquid, as the buoyant force remains constant. This also means that water displacement theory can be used to measure the volume of other liquids by measuring the amount of water displaced when an object is submerged. However, there may be exceptions to this theory in cases where the liquid has unique properties that affect its buoyancy.
Hi,

I assume that you all know the water displacement theory where:

The volume of water displaced is equal to volume of completely submerged object.

Now, my questions is this: does this theory work for other liquids besides water (e.g. mercury, seawater)?
If not, then can you please explain by using example equations/formulae to prove your point.

Many thanks,
Jay

Yes.

Welcome to PF!

Yes, what you said, though a little clumsily worded, does work for other fluids besides water.

## 1. What is water displacement theory?

Water displacement theory, also known as Archimedes' principle, states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid that the object displaces.

## 2. Does water displacement theory only apply to water?

No, water displacement theory can be applied to any liquid. The principle remains the same, where the buoyant force is equal to the weight of the fluid displaced.

## 3. How does water displacement theory apply to other liquids?

The principle of water displacement applies to other liquids in the same way as it does to water. The buoyant force is still equal to the weight of the fluid displaced, regardless of the type of liquid.

## 4. Are there any exceptions to water displacement theory for other liquids?

In general, water displacement theory applies to all liquids. However, there may be some exceptions in cases where the liquid is highly compressible or has unique properties that affect its buoyancy.

## 5. Can water displacement theory be used to measure the volume of other liquids?

Yes, water displacement theory can be used to measure the volume of other liquids. By measuring the amount of water displaced when an object is submerged in the liquid, we can calculate the volume of the liquid using the principle of water displacement.
