By the end of this course you should be able
to answer some interesting questions
Why sometimes air simply leaks out of a cycle tube while at other times it
comes out with a burst?
How are atoms arranged inside a solid?
How we can produce interesting combination of properties?
13
Why did Titanic sink?
14
Artificial rain?
A giant "dragon" spewing out artificial rain over rural
crop of Vidalia sweet onions
15
Concept of stability and metastability
What do we mean by stable state?
How we define metastable state?
Some materials tend to remain in metastable
State for years and years!! Why???

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