Does cold temperature affect the elasticity of a rubber band.

Rubber band elasticity and temperature.

Use a spring scale to measure the maximum force that a rubber band can withstand before breaking. Today rubber bands are most commonly used to hold multiple items together. When you stretch and release a rubber band why does it change temperature. The heated rubber bands were the most elastic.

Rubber elasticity refers to a property of crosslinked rubber. The rubber band s elasticity water resistance and lightness have made it a universal commodity. Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube. The hypothesis was supported by our experiment.

Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and. This activity brought to you in partnership with science buddies. The rubber bands in freezing water were the opposite with a stretching length of 9 50 o o5 cm 0 c. Stretching to the farthest extends of 17 90 o o5 cm 100 c.

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. Do you think that the force required to break a rubber band will change with temperature. Effect of temperature on the elasticity of a rubber band table. Modifications to the original rubber band patented in england on march 17 1845 by stephen perry include aerobic bands bracelets and projectiles.

Dependent variable temperature is defined as the temperature of the water that the rubber band is submerged in independent variable. This can be repeated many times with no apparent degradation to the rubber. 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. 3 take one rubber band from the three and cut it at a point.

Rubber band elasticity and temperature. 1 take out rubber band from the box and group them into threes for three trials at each temperature. Kimberley answer yes a rubber band will actually become softer or easier to stretch when the temperature gets colder. 2 place the first three rubber bands in a room temperature for 10 minutes.

The way to think of the elasticity is in terms of entropy which is basically a measure of disorder. 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.
