Is it heat expands and cold contracts
WitrynaIf mechanical stress is applied to the elastomer or rubber string which is subsequently heated, the polymer contracts as a result of the intensive growth of the role of the entropy factor (the maximum entropy in polymers occurs in the coil-like ordering of the molecules). This effect is also utilized in the rubber-band heat engine (Feynman wheel). Witryna9 kwi 2015 · The rubber band actually expands when it gets colder! This seems counterintuitive because most materials expand when they are heated and contract when they get cold. This occurs because of the ...

Witryna16 kwi 2009 · Heat expands, cold contracts. Physiologically this translates into the use of heat as a vasodilator – bringing nutrient rich blood to surface areas – and the use of cold acting as a vasoconstrictor – driving blood to the body’s core – nourishing and protecting the inner organs of the body. Used alone, heat can help to relax aching ... http://scienceline.ucsb.edu/getkey.php?key=2406
