Thermodynamics mainly deals with:

Options

A. interrelation of various forms of energy and their transformation from one form to another
B. energy changes in the processes which depends ony on initial and final states of the microscopoic systems containing a few molecules
C. how and ay what rate these energy transformation are carried out
D. the system in equilibrium state or moving from one equilibrium state to another equilibrium state

Answer

A, D

Explanation

Thermodyanmics deals with interrelation of various from of energy and their transformation into each other. It also deals with thermal or mechanical equilibrium. However, it does not tell any thing about the rate of reaction
