Rubber Band Elasticity And Temperature Conclusion

1 take out rubber band from the box and group them into threes for three trials at each temperature.

Rubber band elasticity and temperature conclusion. This will be the main temperature for the experiment. How does the rubber band feel now. Use a spring scale to measure the maximum force that a rubber band can withstand before breaking. Does cold temperature affect the elasticity of a rubber band.

Rubber band elasticity and temperature from science buddies science activities for all ages from science buddies. Record your data in your notebook. 2 place the first three rubber bands in a room temperature for 10 minutes. 3 take one rubber band from the three and cut it at a point.

Now put the shoebox into the refrigerator for 15 minutes. For each temperature we collected data for two colored rubber bands and two natural rubber bands. When the rubber bands were removed from their apparatuses a measurement was taken pre stretching. One measures the stiffness by changing the force while.

Results table graph summary of results. Method materials procedure diagram. Rubber 1 was not as slack as thin and had a smaller circumference than rubber 2. This activity brought to you in partnership with science buddies.

After 15 minutes remove the shoebox and measure the length of the rubber band again. Put another way since you re asking about elasticity in the context of a hot and a cold rubber band loaded by the same weight i should emphasize that one can t directly measure a system s stiffness by keeping the force constant and observing the displacement when changing other things. When the rubber bands were attached to the flags the total circumference of the rubber bands then became 0 30 m 0. Kimberley answer yes a rubber band will actually become softer or easier to stretch when the temperature gets colder.

The rubber bands in freezing water were the opposite with a stretching length of 9 50 o o5 cm 0 c. Then measure the length of the rubber band with the ruler. The heated rubber bands were the most elastic. The effect of temperature on the.

The rubber bands were suspended from a secured pencil and 400g of weight were hung from the pencil. Do you think that the force required to break a rubber band will change with temperature. Introduction background statement of the problem hypothesis. Effect of temperature on the elasticity of a rubber band table.

The way to think of the elasticity is in terms of entropy which is basically a measure of disorder. Five shots with. Stretching to the farthest extends of 17 90 o o5 cm 100 c. Perform multiple trials with rubber bands at different initial temperatures.

Allow the rubber band to stretch for three minutes at room temperature. The hypothesis was supported by our experiment. Anu rajendran lauren janes amanda hermens.
