There are multiple questions here . i am allowed to answer only 1 at a time. I will answer 1st question for you.Please ask other as different question

1.

Vaccum cleaner is a most common example. Inside the vacuum cleaner,there is a fan that blows air. For fan to blow air, it needs to draw air in. So vaccum cleaner sucks up air and along with it dirt and dust. This is how it cleans. Thus a low pressure is created inside vaccuum, this low pressure air caused by the air going into the vacuum cleaner draws up small objects which then get trapped in bags, canisters or filters.

There is something called Vacuum suction which is used in many industries to move materials around.

Another example is a milking machine which uses low air pressure inside to create suction to milk a cow. The milk can also be moved to a large holding tank using vacuum pressure.
