Study Notes
Vacuums and Matter
- A vacuum is a space with little to no matter or air, but it's impossible to completely remove all particles of matter.
- Everything on Earth that has mass and takes up space is considered matter, including air, which is a type of gas.
Creating a Vacuum
- A vacuum can be created using a vacuum pump that sucks air out of a sealed container, leaving little to no pressure inside.
Properties of a Vacuum
- In a vacuum, there is little to no air pressure, allowing enclosed objects to expand more easily.
- Without outside air pressure, the pressure inside an object, such as a balloon, increases, causing it to inflate further.
Vacuums in Space
- The biggest and best vacuum is found in outer space, where there is a near-complete absence of matter and air.
