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.
Indoor molds exposure leads mostly to upper respiratory tract symptoms. Long-term exposure to indoor molds is certainly unhealthy to anyone, but some groups will develop more severe symptoms sooner than others, including: Infants and children.
