This is a volume of space that is empty of matter. Example: Sound cannot travel here.
aleksandr82 [10.1K]

Answer:

Vacuum

Explanation:

A vacuum is usually defined as a space in which there is an absence of matter. It can also be said that there is an extremely low amount of pressure due to which the particles present in it are not affected by any type of process that occurs in space. The value of pressure is lower than the value of normal atmospheric pressure.

For example, sound cannot travel in space because there is no medium such as water and air through which the sound waves can propagate.
