Coal is a highly hygroscopic and porous material. In situ normally it is saturated with water and acts like an aquifer. Water in coal influences many aspects of coal technology, like bulk flow properties, abrasiveness during grinding, spontaneous heating and combustion rates. Water in coal, however, does not only influence coal technology.

Water has a very high specific heat capacity of 4.1814 J/(g·K) at 25 °C – the second highest among all the heteroatomic species (after ammonia), as well as a high heat of vaporization (40.65 kJ/mol or 2257 kJ/kg at the normal boiling point), both of which are a result of the extensive hydrogen bonding between its molecules. These two unusual properties allow water to moderate Earth's .

Effect of Soil texture on water Storage and Water Movement. Differences in the ability of different soil types to store water do exist. Sandy soils hold about 101.6 mm (4 in) of available water within the depth of root penetration about 1.22 m (48 in), loams and clay loams 152.4 to 177.8 mm (6 to7 in), and clays about 203.2 m (8 in).
