Crystals will begin to form. crystals form from c<span>ertain molecules in the liquid gather together as they attempt to become stable. they </span>do<span> this in a uniform and repeating pattern that </span>forms<span> the </span>crystal<span>.in nature, </span>crystals<span> can </span>form<span> when liquid rock, called magma, cools.if it cools slowly then </span>crystals<span> may</span>form<span>.</span> hope it helps :)
The reaction that releases energy as heat is called an Exothermic reaction. This reaction does obey the law of conservation by preserving the energy present in the molecule and converting it to thermal heat to maintain it's from. Most reactions obey the law of conservation of energy.
