Introduction to Thermodynamics

Thermo means heat and dynamics means motion
resulting into mechanical work. Hence the word 'Thermodynamics' literally means that branch of science which deals with the conversion of heat into mechanical work and vice – versa.

"Thermodynamics is that branch of science which deals with quantitative relationships between heat and other forms of energy."

    When we confine our study to chemical changes and chemical substances only, the restricted branch of thermodynamics is known as Chemical Thermodynamics.
