Why the gases are more compressible than the liquids Class 9?
The intermolecular space between the gas particles is very large as compared to the intermolecular space between the liquid particles. Hence, gases are more compressible.
Why are gases highly compressible but not liquids?
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.
What is called compressibility?
Compressibility is the property of being reduced to a smaller space by pressure. The compressibility of fluid is basically a measure of the change in density that will be produced in the fluid by a specified change in pressure.
What are fluids Grade 9?
Fluids : Fluids are the substances which have tendency to flow. A liquid is a fluid form of matter which occupies the space of the container.
Is compressible but not liquid?
On applying pressure, the gaseous particles come together, where as in liquids and solids, the particles are very close and hence cannot be further brought closer. Hence gases are compressible but not liquids.
Which gases are compressible but not liquid?
Gas is more compressible than liquids because in gases the molecular force of attraction between particles is almost negligible and the intermolecular spaces are negligible. So if we force a gas into another the particles will not get attracted and they will flow in any direction they want.
What is compressibility and example?
: capability of compression : the ability of something (such as a fluid) to be reduced in volume or size under pressure When that water expands, it turns into a gas. The gas forms bubbles and those bubbles dilute the compressibility of the brake fluid. —
Where we use compressibility in our daily life?
We use this property in our daily lives. Natural gas is compressed to liquid gas and stored in gas cylinders and used as fuel. By compression of air we can blow things like balloon and at the same time deflate them. By compression of gases we can pump air into the bicycle tire using a pump.
What is Class 9 Archimedes Principle?
Hint: Archimedes’ principle states that, any object completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward or buoyant force. If the body is completely submerged, the volume of fluid displaced is equal to the volume of the body.
What is acceleration for class 9th?
Acceleration is defined as. The rate of change of velocity with respect to time. Acceleration is a vector quantity as it has both magnitude and direction.
Are liquids compressible?
Liquids are non-compressible and have constant volume but can change shape. A liquid’s shape is dictated by the shape of the container it is in.
Why do solids have high density?
The particles in solids are very close together. They are tightly packed, giving solids high densities.
Why is a solid not a compressible gas?
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.
What happens when you put pressure on gas?
When a gas is compressed, as when the scuba tank is being filled, the gas particles are forced closer together. If we put pressure on a solid or a liquid, there is essentially no change in volume. The atoms, ions, or molecules that make up the solid or liquid are very close together. There is no space between the ind… Loading…
How are liquids and solids alike and different?
The intermolecular distances of liquids is small and comparable with those of solids. The difference between solids and liquids is that, in liquids, molecules slide over one another whereas, they occupy stationary position within the atomic or molecular structure in solids.
How does the inverse relationship between pressure and volume work?
In molecular terms, it allows molecules to crowd one another with pressure until liquefaction occurs. Well above liquefaction temperatures the gas complies with Boyle’s Law that states an inverse relationship exists between pressure and volume. The intermolecular distances of liquids is small and comparable with those of solids.
