Thermodynamics is all about,
Flow of heat , into and out of system,
As it undergoes physical/chemical transformations,
Thermodynamics let us know ; if particular ,
Physical/chemical change can occur,
Under a given set of conditions.
In thermodynamics there are three laws empirical ,
one must learn all,
To become a innovative physical chemist,
Boundary and surroundings are environment of system,
Diathermal boundary wall provide no insulation to system,
Adiabatic process won’t allow heat to flow in and out of system.
Three themodynamics principles,
Are source of my inspiration,
As a student of chemistry ,
Understanding them is my passion,
Since I have to learn them at my own,
Therefore I need to make clear ,
Road mind map of these principles.
Where does heat energy move?,
Heat energy is always moving towards a state,
Concept of state , we can’t abbreviate,
When in contact are two systems ,
And the temperature of one system,
is uniform and same, to connected system,
Thermal equilibrium is said to be attained by two systems,
When the state variables have constant values through out the system,
Themodynamic s equilibrium is said to be attained by a system .
First law of thermodynamics determines internal energy of system,
By taking difference between heat and work of system,
Thermodynamics attempts to explain by its second law,
Why energy always move from high to low?
Why we are not able to reverse the flow?
There is increase in randomness : entropy ,
Is answer to this important query;
Zero is the value of total change in entropy of system,
Plus surrounding ;for a reversible system,
But can we do work against increase in entropy i
Yes ,in doing so, we must put to drain -some energy.
As a scientist we are looking towards perfect model,
Value of entropy is zero at absolute zero for a perfect crystal ,
But with finite number of steps ,
We cant reach absolute zero -temperature which is so magical,
This is what third law of thermodynamics tells us.
Finally it seems we have reached our goal,
Recollecting –learning three laws –empirical,
by making mental- map- road.
Was not that easy , as it looked before.
This master piece on thermodynamics,
This literary humble poem ,by Sukarma Thareja ,
May not be as worth as epics of Mahabharta,
But it is surely not less than,
Epic of struggle of Bhisham Pitahma in Mahabharta.
