Vacuum

C
Venus
D
Model
Explanation: 

Detailed explanation-1: -In science, a vacuum is a space without matter or air. That’s the simple definition, but the truth is that there are always still some particles of matter in a vacuum, but many, many less than the air you’re breathing.

Detailed explanation-2: -A vacuum is a space with nothing in it-not even air. There is no such thing as a total vacuum because it is impossible to remove all the air or particles from a space. But partial vacuums are common. A partial vacuum is a space with almost no air or particles inside.

Detailed explanation-3: -The term “vacuum” is used to describe the zone of pressure below atmospheric pressure. Vacuum is a negative gauge pressure, usually referenced to the existing standard barometric pressure where the equipment will operate.

Detailed explanation-4: -In space, outside of the Earth’s atmosphere, there are almost no molecules in the gas that surrounds the International Space Station. The absence of molecules, means that the air pressure is extremely low – in fact it is almost zero, so it is nearly a perfect vacuum.

Detailed explanation-5: -Vacuums, such as the vacuum of space, contain no matter of any type. Usually, one thinks of the vacuum as having no atmosphere (essentially negligible pressure) but there’s a lack of solids or liquids as well.

Detailed explanation-6: -It will diffuse into space. Space is a near-perfect vacuum-its pressure is nearly zero and it has extremely little matter (in the empty parts, at any rate).
