Question:
Thermodynamics mainly deals with
(i) interrelation of various forms of energy and their transformation from
one form to another.
(ii) energy changes in the processes which depend only on initial and final
states of the microscopic systems containing a few molecules.
(iii) how and at what rate these energy transformations are carried out.
(iv) the system in equilibrium state or moving from one equilibrium state to
another equilibrium state.
Solution:
Option (i) interrelation of various forms of energy and their transformation from
one form to another and (iv) the system in equilibrium state or moving from one equilibrium state to
another equilibrium state are the answers.
