Question
Give the reason for the following:
The kinetic energy of molecules of gases is very large & of solids, the least.
Solution
The Kinetic Energy of molecules of gases is very large because:
-
- The inter-particle space between the particles is maximum.
- The Inter-particle attraction between the particles is negligible. Whereas the kinetic energy of molecules of solids is least.
The Kinetic Energy of molecules of solids is the least because:
- The Inter-particle space between the particles is minimum.
- The Inter-particle attraction between the particles is very strong.
