This is called water of crystallisation and the salt is said to be hydrated. For example, hydrated copper sulfate has the formula CuSO 4 .5H 2 O which formula indicates that for every CuSO 4 in a crystal there are five water (H 2 O) molecules. great clips martinsburg west virginia https://lt80lightkit.com

WebMar 22, 2024 · Crystallisation leads to a dramatic increase in volume which exerts pressure on the surrounding rock, and can eventually fracture the rock. Thermal expansion or insolation usually occurs in arid regions. During the day temperatures rise and heat the rock. As the rock heats up it expands. WebAug 30, 2012 · 1. As ice occupies 9% more volume than water, it exerts pressure within the joints. 2. When water freezes within the rock it attracts small particles of water, creating increasingly large ice crystals. In either case the process slowly widens the joints and, in time, causes process of rock to shatter (or disintegrate) from the main rock.

Crystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
