🌌The vacuum is not truly empty but filled with invisible air molecules.
💸Creating a vacuum involves removing air to eliminate disturbances.
📈Perfect vacuums are unattainable, but extremely low particle densities can be achieved.
🎡Intergalactic space is almost completely empty.
🎒In a vacuum, sound cannot travel, objects get compressed, and temperature loses its meaning.
What is a vacuum?
—In common terms, a vacuum refers to the lack of any visible matter. However, it is not truly empty but filled with invisible air molecules.
How is a vacuum created?
—Creating a vacuum involves pumping out and extracting air from an object to remove disturbances and achieve low particle densities.
Can a perfect vacuum be created?
—No, perfect vacuums are unattainable. However, we can achieve extremely low particle densities.
What is intergalactic space?
—Intergalactic space is the space that exists between galaxies. It is almost completely empty.
What happens in a vacuum?
—In a vacuum, sound cannot travel, objects get compressed due to atmospheric pressure, and temperature loses its meaning.
