The student will understand the adverse effects of excess humidity and will recognize the importance of humidity control in the home. Define humidity and explain its relationship to heat. Describe the adverse effects of improper humidity levels. List ways of controlling humidity in the home. Humidity refers to the amount of moisture in the air.
Warm air is capable of holding much more moisture than cool air.
Relative humidity refers to the amount of moisture air holds in relation to the amount it could possibly hold at a given temperature. When the air reaches dew point, it is said to be saturated. Condensation shows up as small droplets of water. It forms on surfaces in the home that are cooler than air temperature. An outside example is dew on the grass in the morning.
