Experiment to Prove that Glass is Denser than Air

To demonstrate that glass is denser than air, we can conduct a simple experiment using a glass object, such as a glass bottle or a glass marble, and a container filled with air. The experiment can be summarized in the following steps:

Materials:
- Glass object (e.g., glass bottle, glass marble)
- Container (e.g., transparent beaker, glass jar)
- Water
- Weighing scale
- Measuring cylinder

Procedure:

1. Setup:
- Fill the container with air to create a medium for the glass object to be placed in. Ensure that the container is clean and dry.
- Fill the measuring cylinder with water and place it in a larger container to collect any spilled water during the experiment.
- Place the glass object on the weighing scale and record its mass.

2. Measurement of Water Displacement:
- Gently lower the glass object into the container filled with air, ensuring that it does not touch the sides or bottom of the container.
- Observe the water level in the measuring cylinder and record the initial reading.
- Carefully submerge the glass object into the water, making sure it is completely covered.
- Observe the rise in water level in the measuring cylinder and record the final reading.
- Calculate the difference between the final and initial water levels to determine the volume of water displaced by the glass object.

3. Calculation of Density:
- Use the formula to calculate the density of the glass object:
Density = Mass / Volume
The mass of the glass object is obtained from the weighing scale, and the volume is the water displaced by the object.

Explanation:

When the glass object is placed in the container filled with air, it displaces the air, causing the water level in the measuring cylinder to rise. This displacement of water shows that the glass object occupies space in the container, demonstrating its density.

The calculated density of the glass object can be compared to the density of air to confirm that glass is denser. The density of air at room temperature and atmospheric pressure is approximately 1.2 kg/m³. If the density of the glass object is higher than this value, it confirms that glass is denser than air.
