A change of state is usually accompanied by a change of specific heat. The specific heat of ice is 0.5; while that of water is 1.0. 5. Wattage required to change a liquid to a vapor state at constant temperature.Heat of vaporization (Btu/lb) x Weight of material to be vaporized (lb/hr) 3.412 btu/watt hr.t requires 965 Btu to change one pound of water at 212 F to one pound of steam at 212 F. 6. Wattage to counteract liquid surface losses: Total liquid surface area (sq. ft.) x Loss rate at final temperature (watts/sq. ft.) 2 = Watts 7.
Some people are sensitive to molds. For these people, exposure to molds can cause symptoms such as nasal stuffiness, eye irritation, wheezing, or skin irritation. Some people, such as those with serious allergies to molds, may have more severe reactions.
Allergy and irritation are the most common symptoms of mold exposure. Less common effects of mold exposure include infections and illness. Serious infections from molds are relatively rare and occur mainly in people with severely suppressed immune systems. Illness has been reported from workplace exposures to mold.
