Rubber Band Elasticity And Temperature

This can be repeated many times with no apparent degradation to the rubber.

Rubber band elasticity and temperature. The way to think of the elasticity is in terms of entropy which is basically a measure of disorder. Use a spring scale to measure the maximum force that a rubber band can withstand before breaking. 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.

1 take out rubber band from the box and group them into threes for three trials at each temperature. 3 take one rubber band from the three and cut it at a point. When you stretch and release a rubber band why does it change temperature. Do you think that the force required to break a rubber band will change with temperature.

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. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and. The rubber bands in freezing water were the opposite with a stretching length of 9 50 o o5 cm 0 c. Perform multiple trials with rubber bands at different initial temperatures.

Rubber band elasticity and temperature. This will be the main temperature for the experiment. 2 place the first three rubber bands in a room temperature for 10 minutes. Modifications to the original rubber band patented in england on march 17 1845 by stephen perry include aerobic bands bracelets and projectiles.

Does cold temperature affect the elasticity of a rubber band. Stretching to the farthest extends of 17 90 o o5 cm 100 c. Kimberley answer yes a rubber band will actually become softer or easier to stretch when the temperature gets colder. Dependent variable temperature is defined as the temperature of the water that the rubber band is submerged in independent variable.

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. Rubber elasticity refers to a property of crosslinked rubber. This activity brought to you in partnership with science buddies. The rubber band s elasticity water resistance and lightness have made it a universal commodity.
