Concept of stability and metastability
What do we mean by stable state?
How we define metastable state?
Some materials tend to remain in metastableState for years and years!! Why???

Otherwise Unstable
Minimum Energy – STABLE EQUILIBRIUM
Maximum Energy – UNSTABLE EQUILIBRIUM
Global Minimum - Most STABLE
Local Minimum - METASTABLE
