Why are solids not compressible Class 9?

Solids are not compressible because, In solids the atoms of the molecules are bounded by strong bonds.

Why is a solid not compressible but gas is?

The inter-particles spaces in solids is minimum and they are closely packed and hence, they cannot be compressed because there is no place for particles to move, while the gases are not compactly packed, the particles of gas can move around freely and hence they are highly compressible.

Why compressibility of solid is negligible?

Compressibility is the ability to be reduced to a lower volume when force is applied. Solids are incompressible as their particles are held together. So, we can tell that compressibility is negligible in solids.

Do compressible is a solid?

(a) In minute pores of sponge air is trapped. When pressed, air is expelled out so it is compressible. It is a solid as it has definite shape and volume.

Why solids are less compressible than that of liquids or gases?

Matter is compressible due to the intermolecular spaces in it (i.e. spaces between its molecules). Gases are the most compressible because there are very large intermolecular spaces. Solids are the least compressible because the intermolecular spaces are very tiny, not enough to allow visible compression.

Why is sponge considered as solid though it can be compressed?

When we compress the sponge, the trapped air inside the minute holes of the sponge gets expelled out. – As we have seen, a sponge regains its shape and mass remains the same after the compression. Therefore, a sponge can be considered as solid though it is compressible.

Why is sponge considered a solid?

The sponge is matter and considered as solid because it has a definite volume and shape does not change unless compressed. A sponge can be compressed easily even though it can be considered as solids because they have minute pores in it which are filled with air.

Why are liquids more compressible than solids?

Liquids have larger inter-particle distance (intermolecular or interatomic) compared to Solids. Because in solids, the particles are closely held by strong forces, the intermolecular or interatomic distance is not reduced that much. Hence, liquids are more compressible.

Is solid not compressible?

Solids are non-compressible and have constant volume and constant shape. Liquids are non-compressible and have constant volume but can change shape. Gases do not have a constant volume or shape; they not only take the shape of the container they are in, they try to fill the entire container.

Why solids such as cotton and sponge can be compressed?

sponge is a porous solid. sponge has minute holes in which air is trapped when we press it the air is expelled out and we are able to compress it. A sponge can be compressed easily but still we count them in solids because they have minute pores in it which are filled with air.

Why solids are not compressible while gases are compressible?

Solids are not compressible because the molecules are tightly packed and the inter molecular space is less or is negligible . To understand it better take a look at the following image. Now you see the gases have large space hence are compressed to a large extent.

Why is matter compressible?

Matter is compressible due to the intermolecular spaces in it (i.e. spaces between its molecules). Gases are the most compressible because there are very large intermolecular spaces. Solids are the least compressible because the intermolecular spaces are very tiny, not enough to allow visible compression.

How do gases differ from solids and liquids?

To understand it better take a look at the following image. Now you see the gases have large space hence are compressed to a large extent. The liquids have space more than solids but less than gases hence are compressible to less extent. But the solids have negligible space and hence are not compressible.

Why do solids and liquids expand with temperature?

Most solids and liquids expand with temperature (ice is an exception – it contracts with increased temperature) because there is more energy in the particles, and therefore they move faster and take up more space.
