What is the independent variable in the Cartesian diver experiment?

How does the Cartesian diver experiment work?

The Cartesian diver, consisting of a plastic medicine dropper and a metal hex nut, will float or sink in the bottle of water depending on the water level in the bulb of the dropper. … The more water that is inside the diver, the less buoyant it becomes and the diver sinks.

What is the purpose of the Cartesian diver experiment?

A Cartesian diver or Cartesian devil is a classic science experiment which demonstrates the principle of buoyancy (Archimedes’ principle) and the ideal gas law.

What does the Cartesian diver demonstrate about Pascal’s principle?

The Cartesian diver is a classic demonstration which effectively demonstrates Pascal’s Principle, which states that Pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid.

How does a Cartesian diver work gas laws?

The Cartesian diver demonstrates not only buoyancy, but the implications of the ideal gas law and Pascal’s principle as well. Squeezing on the top of the sealed plastic container decreases the volume and therefore increases air pressure above the water. … This decreases the buoyant force on it enough to cause it to sink.

What variables affect an object’s ability to float?

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.

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 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.

How does this experiment relate to what you’ve learned about submersible technology such as submarines and ROVs?

How does this experiment relate to what you’ve learned about submersible technology such as submarines and ROVs? This relates to submarines and ROVs because the packet being submerged under the water is sort of like how the two work.

What law is the Cartesian Diver?

Pascal’s law states that a pressure applied at any point on a confined incompressible fluid is transmitted equally throughout the fluid. When the bottle is pressurized (squeezed) the pressure within the entire bottle and Cartesian diver is increased.

What happens to the density of the diver when the bottle is squeezed?

Squeezing the bottle causes the diver (the eye dropper) to sink because the increased pressure forces water up into the diver, compressing the air at the top of the eye dropper. This increases the mass, and density, of the diver causing it to sink.

What variable are you changing when you squeeze the bottle?

When you squeeze the sides of the bottle, you are increasing the pressure on the liquid inside. That increase in pressure is transmitted to every part of the liquid. That means you are also increasing pressure on the eye dropper itself.
