Объяснение:
It is not possible to create a model of a complete vacuum using just a box lid and marbles because a complete vacuum is defined as a space devoid of any matter, including air and marbles. However, you can use the box lid and marbles to create a simple model that demonstrates the concept of a partial vacuum or low pressure.
Start by placing the box lid upside down on a flat surface.
Scatter a few marbles randomly on the surface of the lid.
Use a vacuum cleaner or a vacuum pump to suck the air out from under the lid. If you don't have a vacuum cleaner or pump, you can also try using a drinking straw to suck the air out manually, although this will not create a very strong vacuum.
As you remove the air, you will notice that the marbles start to move towards the center of the lid. This is because the air pressure on the outside of the lid is greater than the pressure on the inside, causing the lid to curve downwards and creating a low-pressure area in the center.
If you continue to remove the air, you will eventually reach a point where the marbles come to rest in the center of the lid. This is the point of maximum vacuum that you can achieve with this simple model.
While this model does not represent a complete vacuum, it can help you understand the basic principles of pressure and vacuum.
