Question

List 10 properties of Gases??

Answer 1

1.Atoms are very freely arranged.
2.A gas is easily compressible.
3.they form homogeneous mixtures with each other.
4.they are expandable.
5.can be diffused into other gas.
6.on cooling changes to liquid.
7.can easily move in all directions.
8.it had no surface of its own.
9.no definite shape.
10.no definite volume.

Answer 2

Properties of Gases:

1. A gas has no definite shape or volume of its own. It acquires the shape of the container.

Reason: Intermolecular attraction is the weakest in gases whereas intermolecular separation is the largest. Hence, molecules in a gas move very fast and the gas expands to fill all the space available.

2. A gas has no surface of its own.

Reason: Molecules escape from an open container.

3. A gas is not rigid and is easily compressed.

Reason: Intermolecular separation is very large in gaseous state which can be decreased by applying pressure.

4. A gas can diffuse into another gas.

Reason: Molecules in a gas move very fast. Hence the speed of diffusion is very large.

5. A gas on cooling changes into liquid state.

Reason: Cooling reduces intermolecular separation and increase intermolecular force of attraction.

6. A gas can flow in all directions. It requires a vessel closed from all sides.

7. The molecules are very loosely packed in gases.

8. Gases are not visible.

9. Some gases are air, carbon dioxide, oxygen,.etc...

10. The state of a gas can be completely defined by specifying its temperature, volume, number of moles and pressure.

Hope this helps you! :)
