This is an ideal definition of vacuum. Absolute zero pressure is defined in this space. In practice, achievement of such an environment is impossible because there are always some gas molecules; however, achievement of very low pressures is possible. Today, vacuum systems are manufactured that can generate environments capable of very low molecular separation per unit volume. Pressures lower than the pressure of air atmosphere are called vacuum. The word Vacuum is derived [...]
