Final answer:
Creating a partial vacuum with marbles and a box lid involves displacing air by dropping a marble down a sealed pipe to momentarily change the air pressure, simulating the creation of a partial vacuum.
Step-by-step explanation:
Creating a Partial Vacuum with Marbles and a Box Lid:
To create a partial vacuum using marbles and a box lid, the materials you would typically need include a length of plastic pipe with a diameter of approximately 20 mm, a marble, masking tape, a measuring tape, and a box lid to act as a barrier. The process of creating a partial vacuum would involve setting up a closed environment where the marble can displace air as it moves to create a pressure difference.
Procedure to Make a Partial Vacuum:
- Seal one end of the plastic pipe using the box lid, ensuring that the pipe stands upright and no air can escape.
- Measure the vertical height of the plastic pipe.
- Drop the marble from the top, allowing it to fall to the bottom of the pipe.
- Upon reaching the bottom, the marble will displace some air creating a partial vacuum at the top of the pipe momentarily.
This is a simple demonstration of how a displacement of air can lead to a change in pressure indicating a partial vacuum. In a more controlled experiment, instruments such as vacuum pumps are used to remove air from a sealed container, but this demonstration represents the principle on a basic level.
