Question

How do molecules move as a solid, liquid and gas?

Answer 1

Hint: In nature always the molecules or particles move whatever the state it is present. The movement of molecules is going to change depending on the state they are present. The movement of molecules is going to depend on the space present in between them.

Complete answer:
- In the question it is asked how molecules move different physical states.
- We know that the matter exists in three different physical states and they are solid, liquid, and gaseous.
- In solids the molecules move slowly because the space between the molecules is very less and they are tightly packed in a rigid structure.
- The molecules have vibrational and few molecules have rotational changes also in solid state.
- Coming to liquids, when we apply some amount of heat to solids, the distance between the molecules in solids is going to increase after breaking a few bonds with other molecules.
- As a result the molecules show changes in vibrations, rotations, and translations also.
- The molecules in liquids will be faster than the molecules which are present in solid.
- Coming to gaseous state, in this case the molecules have the changes in vibrations, rotations, and translations also and they will collide and move much faster than the molecules in liquid state.

Note: The mobility of particles is going to depend on which state they are present. The molecules move faster in a gaseous state due to the absence of force of attraction between the molecules when compared to the molecules which are present in solid and liquid state.
