I wander...
which would require more energy, to decompress air like a vacuum or compress air?

See, the problem here is that I read the same thing that Chris said and reach exactly the opposite conclusion! We need more info about what the OP is getting at. Anyway...FredGarvin said:That's the way I read it...
I wasn't thinking the OP really meant energy because in either case, energy could be infinite depending on what you are asking. Ie, since you can't generate a perfect vacuum, you would expend an infinite amount of energy in the attempt. At the same time, compressing air requires more and more energy as well and the OP didn't specify parameters. Here's what I thought of when I read the OP:In reality, it is tougher to pull a vacuum because those systems are much more prone to leaking.
Vacuum refers to a space that is devoid of matter, while compression refers to the process of reducing the volume of a gas or substance by applying pressure.
This ultimately depends on the specific situation, as both processes can require varying amounts of energy. However, in general, compressing a substance usually requires more energy as it involves actively pushing against the natural state of the substance.
No, vacuum and compression are two distinct processes that cannot be used interchangeably. While they both involve manipulating the state of matter, they have different effects and uses.
Creating a vacuum is often used in industrial and scientific processes to remove air or other gases from a space, while compression is used for a variety of purposes such as storage, transportation, and chemical reactions.
In both vacuum and compression, energy is required to manipulate the state of matter. In vacuum, energy is needed to remove the air or gas from a space, while compression requires energy to apply pressure and change the volume of a substance.
