Thermodynamics deals only with the ____________scale response of a system which we can observe and measure in experiments.

The second law of thermodynamics says:

This quantity is the energy associated with a chemical reaction that can be used to do work, and is the sum of its enthalpy (H) and the product of the temperature and the entropy (S) of the system.

Dg < 0

If the equilibrium state is _________, the system will return to that state when a small disturbance is imposed upon it.

Refers to a condition in which the state neither changes with time nor has a tendency to spontaneously change

Equilibrium can only occur in a _________ system.

Mention the 4 types of equlibrium

The Second Law of thermodynamics can be expressed in terms of :

Irreversible processes are...

ย€œFor any reversible process, the entropy of the universe remains_________, while for any irreversible process, the entropy of the universe_______โ€.

It is a measure of chemical potential in the form of 'adjusted pressure.' It directly relates to the tendency of a substance to prefer one phase (liquid, solid, gas) over another.
