How Poison Ivy Works | HowStuffWorks - Science

The culprit behind the rash is a chemical in the sap of poison ivy plants called urushiol (oo-roo-shee-ohl). Its name comes from the Japanese word "urushi," meaning lacquer. Urushiol is the same substance that triggers an allergic reaction when people touch poison oak and poison sumac plants.

History. The concept of residence time originated in models of chemical reactors. The first such model was an axial dispersion model by Irving Langmuir in 1908. This received little attention for 45 years; other models were developed such as the plug flow reactor model and the continuous stirred-tank reactor, and the concept of a washout function (representing the response to a .

Heat Transfer: From Hot to Not - Lesson - TeachEngineering

Beyond chemical reactions, heat is exchanged for physical reactions, too. Some examples include dissolving one chemical in another, or phase changes between solid, liquid and gas. Heat of reaction is the amount of heat energy generated or absorbed for a given physical or chemical reaction. Reactions can either give off heat or they can absorb heat.
