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.
Not everyone responds to mold exposure the same way. Symptoms range from mild to severe. Children, older adults and immuno-compromised individuals are at greatest risk of developing problems. People with severe mold allergies can develop fever or shortness of breath. Symptoms can include: sore throat; bleeding gums; runny, itchy or stuffy nose; nose bleeds; difficulty breathing; wheezing; coughing; swelling of the lungs; and even bleeding in the lungs. A rare inflammatory lung disease called hypersensitivity pneumonitis. can also be caused by mold exposure.
