Understanding Helium Gas as Matter
Helium gas is classified as matter due to its fundamental properties. Here's a detailed breakdown:
Mass and Volume
- Helium has a definite mass, even though it is a light gas.
- All matter possesses mass, which is a key characteristic that defines it as matter.
- Additionally, helium occupies space, which is another essential property of matter.
Definite Volume
- Although helium gas does not have a definite volume in the sense of a fixed shape, it still occupies space within a container.
- Gases expand to fill the volume of their containers, but they are still considered to have volume since they displace air and other gases.
Compressibility
- Helium can be compressed easily, which is a characteristic of gases.
- While compressibility is notable, it does not define matter; rather, it describes the behavior of gases.
Conclusion
- The key reason helium is classified as matter is its mass and the ability to occupy space.
- Thus, the correct answer is option 'A': "It has mass and occupies volume," highlighting the essential properties of all matter.
