It is because the particles of gas move around all the time because of more interparticle spaces and also they spread anywhere because of which it fills up the container.

Volume of Gases: Take the volume of container

Gas is one of the three states of matter, along with liquid and solid. Unlike solids and liquids, gases have the unique property of being able to expand and occupy any available space. The volume of a gas refers to the amount of space it occupies.

The volume of gases is determined by the size of the container in which they are held. This means that the volume of a gas can vary depending on the size and shape of the container.

Explanation:

1. Definition of volume:
- Volume is a measure of the amount of space occupied by a substance.
- In the case of gases, volume refers to the space occupied by the gas molecules.

2. Definite volume:
- Gases do not have a definite volume.
- Unlike solids and liquids, which have a fixed shape and volume, gases can expand and fill the entire space available to them.

3. Almost Nil volume:
- It is incorrect to say that the volume of gases is almost nil.
- Gases can occupy a significant amount of space, depending on the conditions.

4. Large volume:
- Gases have the ability to occupy a large volume.
- This is because gas molecules are far apart and move freely in all directions.

5. Volume of the container:
- The volume of a gas is determined by the size of the container in which it is held.
- If the container is larger, the gas will occupy a larger volume.
- If the container is smaller, the gas will occupy a smaller volume.

Conclusion:
The correct answer is option 'D' - Take the volume of container. The volume of gases is not definite or almost nil, but rather depends on the size of the container in which they are held. Gases have the ability to expand and occupy any available space, and their volume can vary depending on the size and shape of the container.
