Capitalization is used when an item is expected to be consumed over a long period of time. If a cost is capitalized, it is charged to expense over time through the use of amortization (for intangible assets) or depreciation (for tangible assets).
As water temperature rises, oxygen solubility decreases. On a cool summer night, a lakeâs temperature might be 60Â° F. At 100% air saturation, this lakeâs dissolved oxygen levels would be at 9.66 mg/L. When the sun rises and warms up the lake to 70Â° F, 100% air saturation should equate to 8.68 mg/L DO Â³.
It is the unique properties of the water molecule which causes water to contract down to 40 degrees F and then to begin expanding at 39 degrees F to 32 degrees F that makes this process possible without freezing the lake through.
