Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and. Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube. Elasticity of the rubber band is defined as the maximum length the rubber band stretches from its initial length when weight is placed on it. The hypothesis was supported by our experiment.
Kimberley answer yes a rubber band will actually become softer or easier to stretch when the temperature gets colder. Modifications to the original rubber band patented in england on march 17 1845 by stephen perry include aerobic bands bracelets and projectiles. It can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length. Effect of temperature on the elasticity of a rubber band table.
27 feb 2020 by john staughton when you stretch a rubber band the volume and entropy decrease and the temperature rises whereas when you allow a rubber band to relax the volume and entropy increase so the. Use a spring scale to measure the maximum force that a rubber band can withstand before breaking.
