Question
As compared to gases, liquids are:
As compared to gases, liquids are:
- Incompressible
- Compressible
- More compressible than gases
- Less compressible than gases
Hint:
Gases and liquids differ in the strength of their intermolecular forces.
The correct answer is: Less compressible than gases
- As compared to gases, liquids are less compressible than gases.
- Compressibility is considered as a measure of the relative volume change of a substance whether it is a fluid or a solid in respone to the pressure.
- As compared to gases, liquids have a definite volume and their attractive forces are not strong enough to keep the molecules at a certain place. Therefore, these molecules slide over each other. And so they are capable of taking the shape of the container.
- Since gases are less dense and adjust anywhere they do not possess this property. Liquids being denser, are less compressible than gases.
The intermolecular forces are responsible for giving shape and strength to the substance.

Brownian motion is seen in _______
The atomicity of a molecule is the total number of atoms present in it.
Sulphuric acid (H2SO4) has one sulphur atom, two hydrogen atoms, and four oxygen atoms in it. Hence, a total of 7 atoms are present. Therefore, the atomicity of H2SO4 is seven.
