We can rewrite as H1– H2= ΔH = q Where ΔH represents the increase in the enthalpy of a system when it changes from state 1 to state 2. Like internal energy, enthalpy is also an extensive property as well as a state function. The absolute value of enthalpy cannot be determined. Ho...

Energy values, as you know, are all relative, and must be defined on a scale that is completely arbitrary; there is no such thing as the absolute energy of a substance, so we can arbitrarily define the enthalpy or internal energy of an element in its most stable form at 298K and 1 ...

say the universe as a system moves further away from entropy even as areas within it increase in entropy. Others consider the universe as part of a larger system. Still, others say the possible states do not have equal likelihood, so ordinary equations to calculate entropy do not hold valid...
