For the following example,identify the following. H 2 O(l)→ H 2 O(s)

The change from liquid to solid indicates a decrease in entropy (negative ΔS). Additionally, if the process is spontaneous (i.e. occurs without the input of external energy), then the overall change in energy (enthalpy and entropy) must be negative (ΔG = ΔH - TΔS); therefore, a negative ΔH is also required.
