# What law does the Cartesian Diver follow?

## Is the Cartesian diver Boyle’s Law?

The Cartesian diver demonstrates the concept of density as a function of mass and volume. … This added pressure decreases the volume of the gas in the bottle, including the gas in the medicine dropper. This is Boyle’s Law.

## What three laws principles can explain how a Cartesian diver works?

Vv’hen you build a Cartesian diver, you are exploring three scientific properties of air: (1) Air has weight (2) Air occupies space (3) Air exerts pressure. Generally speaking, an object will float in a fluid if its density is less than that of the fluid (densltyemass/volume).

## How does the Cartesian diver demonstrate Archimedes Principle?

A Cartesian Diver is a closed system used to demonstrate Archimedes’ Principle. Cartesian divers are made with an air bubble, which causes them to just float when placed in water. … As the bubble is compressed the diver fills with water causing it to lose buoyancy and sink.

## How does Boyle’s law relate to Cartesian diver?

Boyle’s Law describes the relationship between pressure and volume. Increasing pressure on a gas will decrease its volume. When the sides of the diver are pressed, the water is forced into the dropper, decreasing the volume of air in the dropper. This makes it more massive and dense, causing it to sink.

## What happens to the medicine dropper as you press the container and release it?

So when you push more water inside the dropper, you increase its overall density. … Release the pressure on the bottle’s sides and you stop forcing water inside the eye- dropper. The air inside it will now push out the extra water again, and the eye-dropper will rise.

## What is meant by Cartesian diver?

: a small hollow glass figure placed in a vessel of water that has an elastic cover so arranged that by an increase of pressure the water can be forced into the figure producing the effects of suspension, sinking, and floating as the pressure varies.

## Why does an empty bottle float?

An empty plastic bottle has air inside it which means that it reduces its density due to which it is able to float over water. … In other words, its density is less than the density of water due to which reason it floats.
