Question & Answer
Choose the Best Answer
Introduce carbon dioxide into the container.
Allow carbon dioxide to escape through the opening.
Place an object on the flat surface.
Observe the object's motion on the surface.
Understanding the Answer
Let's break down why this is correct
Adding carbon dioxide to the container forms a thin gas film on the bottom surface. Other options are incorrect because Some think letting the gas escape first creates a useful film; Placing the object before introducing gas does not create a film.
