Question

The volume of a gas is always the same as the volume of __________.

its container

the atmosphere

its atoms

its molecules

Answer 1

The answer would be A: its container.

Gas will expand to fill whatever container it is put in.

Answer 2

Answer: its container

Step-by-step explanation:

There are three states of matter:

Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and thus have fixed shape and volume.

For example : Copper

Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another. They have fixed volume and take the shape of the container.

For example : water

Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out. Thus they do not have any fixed shape and occupy the whole volume of the container.

For example : Helium gas
