What happens to a marshmallow in a vacuum?

What happens to a marshmallow in a vacuum?

Under normal conditions, molecules of air from the atmosphere (called atmospheric pressure) are pushing on the outside of the marshmallow. When the vacuum packer removes the air that was once pushing on the outside of the marshmallow, the air trapped inside the marshmallow pushes out (expands) causing it to get larger.

What happens when you put marshmallows in a vacuum?

When the air inside the glass container is sucked out, the volume of the container remains the same although there is much less air inside – so the pressure is reduced. The air bubbles inside the marshmallows are therefore at a much higher pressure than the air surrounding the marshmallows,…

Why do marshmallows expand in a vacuum?

By putting the marshmallow in a vacuum, you are removing the atmospheric pressure pushing in on the marshmallow, but the air inside the air bubbles is still pushing outward, so the marshmallow expands. Expansion will stop when the pressure is equalized.
