Why liquid has no definite shape but has definite volume?

Answer 1

Yes, liquids have a definite volume but not a definite shape, compared to solids that have a definite shape and a definite volume or gasses that have neither a definite shape or volume.

Answer 2

The behavior of liquids, where they have no definite shape but do have a definite volume, can be explained by the arrangement and movement of their molecules.

1. Arrangement of Molecules:

• In a liquid, molecules are in constant motion and are free to move past one another. Unlike in solids, where molecules are tightly packed and arranged in a fixed, orderly pattern, the molecules in a liquid are more loosely arranged and can flow and slide over each other.

2. Volume:

• Despite the lack of a definite shape, liquids have a definite volume because the molecules are still closely packed together. The volume of a liquid is determined by the total amount of space the molecules occupy, which remains constant regardless of the container's shape.

3. Intermolecular Forces:

• The molecules in a liquid are attracted to each other by intermolecular forces, such as van der Waals forces and hydrogen bonding. These forces keep the molecules close together and prevent them from spreading out indefinitely, confining the liquid to a specific volume.

4. Adaptability to Container Shape:

• Unlike solids, which maintain their shape regardless of the container, liquids take on the shape of the container they are placed in. This is because the molecules can flow and rearrange themselves to fit the shape of the container while maintaining their volume.

5. Surface Tension:

• Surface tension, a property of liquids, is a result of the cohesive forces between molecules at the liquid's surface. This cohesive force causes the liquid to form a "skin" or surface layer, which gives liquids the ability to maintain a spherical shape (e.g., water droplets) due to the minimizing of surface area.

In summary, liquids have no definite shape because their molecules are free to move and flow past one another, adapting to the shape of their container. However, they have a definite volume because their molecules are closely packed together and confined within a specific space due to intermolecular forces.

Answer 3

Liquids have a definite volume but no definite shape because of the strength of the forces between molecules in a liquid. This allows molecules to easily break free and flow but they do net freely enter the vapor state and float in air unless vaporization conditions are met.

Answer 4

Definite volume: for most practical purposes, liquids are incompressible.

No definite shape: just see what happens when you pour water into a container. It assumes the shape of the container.

Answer 5

This means that a liquid will always have the same amount in its contents, but will take the shape of any container or solid object it is placed on or in.

Answer 6

It means that its science that were talking about

Answer 7

It has a definite volume because it keeps the same amount of mass. It has no definite shape because it can change form depending on the container it's in.

Answer 8

A liquid has the shape of his container; a "free" liquid, without any container has no shape and geometrical dimensions.

Also the volume of the liquid is the volume of the container.

Answer 9

That is right, liquids have a fixed volume but no fixed shape.

Answer 10

They have a shape and volume.
