Q1. How the Vacuum is created ?
V acuum is the highly seen in space where you won't find any of the air presence over there, you can find only the dust, asteroids, planets, micro dust particles which will be moving at a high speed and so that we need to have a high tighten compressed suit to withstand the conditions that are present in space. Due to the pressure variance which is very low so that the particles in the space do not affect any of the process being carried on there. The conditions which are present are below the atmospheric level and it is measured in units of pressure called as Pascal. The vacuum can be created by removing the air present in the atmosphere using the vacuum pumos to reduce the pressure using the fast flow of the fluid. This complete process will be working on the principle know as Bernoulli's Principle.
