Why do solids have a fixed shape and gases have neither a fixed shape nor a fixed volume Class 9?

Why do solids have a fixed shape and gases have neither a fixed shape nor a fixed volume Class 9?

In solids the atoms are tightly packed, thus they have fixed shaped and volume. When it come to liquid the atoms are some more loosely packed, thus they don’t have fixed shape but have fixed volume.

Does gas have a fixed or not fixed volume?

Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.

Why do not gases have a fixed shape?

Solution : Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.

Why are gases highly compressible but not solids or liquids?

Answer: In solids, the particles have highly ordered arrangement because the intermolecular forces between the particles are very strong. Answer: Gases are compressible because the intermolecular space is very large in gases, whereas liquids are not compressible because in liquids, the intermolecular space is less.

Why is gas volume not fixed?

In gases, molecules are loosely packed. The force of attraction between the molecules of gases is least as compared to solids and liquids. The kinetic energies between the molecules is high enough to break away from any boundaries and they move randomly. Thus, gases do not have definite shape and volume.

What has neither a fixed shape nor a fixed volume?

Gases have neither a fixed shape nor a fixed volume, hence gases are highly compressible as compared to solids and liquids.

What has neither fixed shape nor a definite volume?

gas
A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.

What is meant by compressibility why gases are most compressible and solids are least compressible?

Gases are highly compressible because their molecules are far apart from each other. There are a lot of empty spaces between the molecules. They can be easily compressed to a point where the intermolecular distance becomes minimum. this compressibility is lesser for liquids and least for solids.

How do you show gas does not have fixed volume?

To Show that Gases do not have a Fixed Shape or a Fixed Volume. Air is a gas, so we will use air in this experiment. We take two balloons of different shapes and sizes. Let us fill equal amount of air in both the balloons.

Why do gases have neither a nor a fixed volume?

Properties of Matter: Gases. Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.

Why does a liquid have no definite volume?

In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container. Also Know, which state of matter has no definite volume and no definite shape?

Which is state of matter have no definite shape or volume?

In respect to this, which state of matter have no definite shape or volume? A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.

How is a gas different from a solid?

A gas is a substance with no definite volume and no definite shape. Solids and liquids have volumes that do not change easily. A gas, on the other hand, has a vol- ume that changes to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid.
