A vacuum chamber is a sealed container from which air and other gases are removed to create a low-pressure environment. This process allows scientists and engineers to conduct experiments or tests without the interference of air molecules. Vacuum chambers are commonly used in various fields, including physics, materials science, and electronics. These chambers can vary in size and design, depending on their intended use. For example, they may be used to simulate conditions in space, test the durability of materials, or manufacture products like semiconductors. By controlling the pressure inside the chamber, researchers can achieve precise results in their experiments.
