Vacío

The video explains how gases can be extracted in a laboratory setting and discusses the challenges of creating a perfect vacuum. It highlights that even in deep space, a perfect vacuum is unattainable due to the presence of hydrogen atoms.

What is one method to obtain gases in a laboratory?

• By compressing air

• By using a vacuum pump

• By extracting gases from the air

• By heating water

Why is it impossible to create a perfect vacuum?

• Due to technological limitations

• Because of the laws of physics

• Because of the presence of air

• Because some gases always remain

What is a perfect vacuum?

• A space with only hydrogen

• A space with no matter at all

• A space with no air

• A space with low pressure

What can be found even in deep space?

• Oxygen molecules

• Hydrogen atoms

• Carbon dioxide

• Nitrogen gas

How many hydrogen atoms can be found per cubic meter in deep space?

• Millions

• Thousands

• A few

• None
