  • Interesting fact: Cotton crops can be sprayed up to 40 times a year making it the most chemical-intensive crop in the world
    • Intensity (Physics) The amount or degree of energy with which a force operates or a cause acts; effectiveness, as estimated by results produced.
    • Intensity (Photog) The degree or depth of color or shade in a picture.
    • Intensity (Mech) The magnitude of a distributed force, as pressure, stress, weight, etc., per unit of surface, or of volume, as the case may be; as, the measure of the intensity of a total stress of forty pounds which is distributed uniformly over a surface of four square inches area is ten pounds per square inch.
    • Intensity The state or quality of being intense; intenseness; extreme degree; as, intensity of heat, cold, mental application, passion, etc. "If you would deepen the intensity of light, you must be content to bring into deeper blackness and more distinct and definite outline the shade that accompanies it."

  • Interesting fact: Cheetahs make a chirping sound that is much like a bird's chirp or a dog's yelp. The sound is so an intense, it can be heard a mile away.
    • n intensity The character or state of being intense; the quantity or degree of a quality, action, or effect; degree; specifically, a high degree. Intensity (as opposed to extension) is a quantity which is not apprehended by a successive synthesis, but all at once; a quantity the parts of which are not separately identifiable, and which has an absolute minimum.
    • n intensity In physics and mech., the amount or degree of energy with which a force operates or a cause acts; effectiveness, as estimated by the result; the magnitude of a force, measured in appropriate units: as, the intensity of gravitation. In electricity, the intensity of a current is properly its strength (expressed in amperes); in popular language, however, it is often used of the electromotive force or potential-difference of the current, as when a voltaic battery, coupled in series, is said to be arranged for intensity.
    • n intensity Used absolutely: Intense feeling or emotion; also, the exhibition or embodiment of intense feeling or emotion.
    • n intensity In photography, opacity or density, as of a negative. See intensification, 2.
