When ice is placed in warm water it melts. The order or structure of the molecules decreases. This is a natural process explained
by the second law of thermodynamics.
The second law of thermodynamics is also know as the law of
entropy
enthalpy
molecular theory
conservation of energy

Explanation:

Since all energy transfers result in the loss of some usable energy, the second law of thermodynamics states that every energy transfer or transformation increases the entropy of the universe. ... Essentially, living things are in a continuous uphill battle against this constant increase in universal entropy.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
