what is the difference between solid , liquid , gas ?
Solid :- When atoms of any substance is very tightly packed, having no intermolecular space then that substance is called as solid substaces.
- They are rigid in structure.
- Have definite structure and volume.
- Have high density.
Ex:- wood etc.
LIQUID :- When there is some intermolecular spaces between the atoms.
- They are fluid in nature.
- Don 't have definite shape or volume.
- Occupy the shape of the container in which it is kept.
- Less density then solid and more density then liquid.
GAS :- When there is a large intermolecular space between the molecules.
- They are also fluid in nature.
- Have neither definite shape nor volume.
- Have leser densit then water.
Ex :- All atmospheric gases.
@Shubham: Very good answer! Keep posting as your answers are helpful to other users in this forum!
@Suresh: A small addition from my side
Solid, liquid and gas are the three states of matter. The following table lists the differences between these three states of matter.
Packing of particles
Particles are packed very close to each another.
Particles are packed less close to each other.
Particles are packed very far from each other.
Forces of attraction between the particles
Weaker than solids
Shape and volume
Fixed shape and fixed volume
No fixed shape but fixed volume
Neither fixed shape nor fixed volume
Higher than solids
Rate of diffusion
Less than solids
Kinetic Energy of particles
The figure below shows the arrangement of particles in these three states of matter.
Solid Liquid Gas
