Answer: entropy, enthalpy.
Explanation:
Enthalpy is the heat content of a system. Enthalpy is a measure of degree of randomness.
The enthalpy of a thermodynamic system, that is denoted by H, is determined as follows:
H = U + PV
Where,
U is the internal energy of the system
P is the pressure
V is the volume.
The second law of thermodynamics implies that the entropy of an isolated system can never decrease, i.e. the entropy change in an isolated system can only be positive or zero which means a process can be feasible only when the change in the entropy of the universe is positive. the total entropy of an isolated system can never decrease over time, and is constant. In a nutshell, any process that does not violate the second law of thermodynamics must create an increase in the entropy of the universe.
