A large piece of corck weighs (0.285 N in air)When held submerged underwater by a spring scale, as shown, the spring scale reads 0.855 N. Find the density of the cork
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

![### Understanding Electrolysis: Experiment Setup
**Description:**
The image depicts a basic setup for an electrolysis experiment. This setup is commonly used in educational environments to demonstrate the principles of electrolysis, including the movement of ions and the chemical reactions occurring at the electrodes.
**Components:**
1. **Container:** The experiment uses a clear container filled with an electrolyte solution. This could be water with an added salt to enhance conductivity.
2. **Electrodes:** Submerged in the solution are two electrodes. One is typically connected to the positive terminal of a power supply (anode) and the other to the negative terminal (cathode).
3. **Metal Plate:** The container includes a metal plate, which is shown attached above the solution. The plate could be used as one of the electrodes, such as the cathode, where a reduction reaction takes place.
4. **Connections:** Wires are connected to the electrodes, enabling the flow of electric current through the solution.
**Explanation:**
During electrolysis, an electric current is passed through the electrolyte solution using the anode and cathode. Electrochemical reactions occur at the surface of the electrodes. At the anode (positively charged electrode), oxidation occurs, while at the cathode (negatively charged electrode), reduction occurs. This process is fundamental in various applications, including electroplating, purifying metals, and producing chemical compounds.
### Observations:
Upon running the current through the setup, students can observe:
- **Gas Bubbles:** Formation of gas bubbles at the electrodes, indicating a chemical reaction.
- **Metal Deposition:** In some cases, a metal might deposit on the cathode, demonstrating practical applications like electroplating.
### Educational Application:
This experiment provides hands-on learning for students to grasp fundamental concepts of chemistry and physics. It also helps in understanding real-world applications such as metal extraction and refining, manufacturing industries, and even in the context of renewable energy storage solutions.
**Conclusion:**
The electrolysis setup serves as a practical demonstration of electrochemical principles, helping students understand the theoretical concepts through visual and interactive means.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb870117d-bcad-4d3e-b30e-d1462d1fcc01%2F6bf13835-ceee-4f03-8468-d276e2a7c2b3%2Fkyfl8zs_processed.png&w=3840&q=75)
