Why sometimes air simply leaks out of a cycle tube while at other times it comes out with a burst?
By the end of this course you should be ableto answer some interesting questions
How are atoms arranged inside a solid?
13
How we can produce interesting combination of properties?
14
Why did Titanic sink?
15
Artificial rain?
A giant "dragon" spewing out artificial rain over rural crop of Vidalia sweet onions
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???

Activation barrier

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