How do solids have infinite free surfaces?

A solid consist of very rigid and layered structure which allows solid to have number of free surfaces. Since solid consist of infinite number of atom and layers in particular arrangement therefore it contain infinite number of free surface.

What are free surfaces in solids?

In physics, a free surface is the surface of a fluid that is subject to zero parallel shear stress, such as the interface between two homogeneous fluids. Fluidized/liquified solids, including slurries, granular materials, and powders may form a free surface.

How many free surfaces does a solids have?

infinite free surfaces
Solids have infinite free surfaces while liquids have only one upper free surface.

Why do liquids have free surface?

Liquid contains only one free surface. This is because the force of attraction is less between the atom which does not allow it have more than one free surface. For example, liquid occupies the shape of the container in which it is poured.

Why do solids and liquids have open surface while gases do not?

Solids have tight intermolecular bindings while gases have free molecules so they remain apart from each other and so they do not have a surface but solids contain an open surface as the molecules are linked together.

Why the free surface of water is concave?

When liquid water is confined in a tube, its surface (meniscus) has a concave shape because water wets the surface and creeps up the side. Mercury does not wet glass – the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass.

Which state of matter has no free surface?

Gases
Gases have no free surfaces. When heated or cooled, gases expand and contract to a large extent. The density of a gas is almost negligible as compared to a solid or a liquid.

Why do solids have open surface?

becauseThe particles of solids are very close to each other and force of attraction between the particles is very strong. Therefore, solids have a definite compact structure and an open surface. While the particles of gases are very far away from each other and have least force of attraction between them.

Why does mercury not cling to glass?

It is because the force of adhesion between mercury and glass molecules is less than the force of cohesion between mercury molecules. …

Why the surface of the slide should not be oily?

9: Why the surface of the slide should not be oily? Ans. The surface tension will decrease.

Why soap bubbles have two free surfaces?

Soap bubbles try to minimize surface area to gain surface tension energy, but unless they pop the volume of captured air must stay the same. One sphere always has the very lowest surface area with the same volume, but it requires some investment of energy from the collision that may not be available.

How many free surfaces does a solid have?

A solid consist of very rigid and layered structure which allows solid to have number of free surfaces. Since solid consist of infinite number of atom and layers in particular arrangement therefore it contain infinite number of free surface.

Why does a solid have an infinite surface area?

Hope that helps. A lot of naturally occurring solid has practically infinite free surface because of the fractal nature. For example a rock, the finer your measurement unit is, the more surface area you will measure. Surface of a mountain has a fractal nature.

Why do liquids contain only one free surface?

Liquid contain only one free surface because force of attraction is less between the atom which do not allow it have more than one free surface. For example liquid occupy the shape of container in which it is poured.

What is the difference between solids and liquids?

Solids have infinite free surfaces while liquids have only one upper free surface.
