OH NO, IT'S THE E WORD!

Thermo mavens rant about it
Gibbs and Sandler and Van Ness
Give you formula and prose
About this thing that's known as S.

It increases with disorder,
It's a property of state,
It is zero for some crystals,
It's the universe's fate.

It can be dq, dU
and sometimes dH over T,
It's a measure of the extent of
Irreversibility.

It accounts for work that's lost
In engines, blenders, pipes, and flues,
Due to friction or to mixing.
It's a game we always lose.

Its the reason we succumb
To death's inexorable crunch,
It equals k ln omega,
Itis why there's no free lunch.

Super cooled water at -2°C is converted to ice at -2°C. The molal heat capacities of ice and water are 9 and 18 cal/g-mole°C. The heat of fusion of water is 1436 cal/mol.  What are the enthalpy and entropy change for this process?
