Rubber Band Elasticity And Temperature Conclusion

Allow the rubber band to stretch for three minutes at room temperature.

Rubber band elasticity and temperature conclusion.

After 15 minutes remove the shoebox and measure the length of the rubber band again. How does the rubber band feel now. Five shots with. Record your data in your notebook.

Kimberley answer yes a rubber band will actually become softer or easier to stretch when the temperature gets colder. 1 take out rubber band from the box and group them into threes for three trials at each temperature. Use a spring scale to measure the maximum force that a rubber band can withstand before breaking. This will be the main temperature for the experiment.

The hypothesis was supported by our experiment. Then measure the length of the rubber band with the ruler. Perform multiple trials with rubber bands at different initial temperatures. Introduction background statement of the problem hypothesis.

Results table graph summary of results. The way to think of the elasticity is in terms of entropy which is basically a measure of disorder. Stretching to the farthest extends of 17 90 o o5 cm 100 c. The rubber bands were suspended from a secured pencil and 400g of weight were hung from the pencil.

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. One measures the stiffness by changing the force while. 40 m and 0. Anu rajendran lauren janes amanda hermens.

When the rubber bands were attached to the flags the total circumference of the rubber bands then became 0 30 m 0. Now put the shoebox into the refrigerator for 15 minutes. 3 take one rubber band from the three and cut it at a point. 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. The rubber bands in freezing water were the opposite with a stretching length of 9 50 o o5 cm 0 c. The heated rubber bands were the most elastic. The effect of temperature on the.

When the rubber bands were removed from their apparatuses a measurement was taken pre stretching. 50 m and the increase in length of the rubber band was different dependent on which rubber band was used see table. 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.

Do you think that the force required to break a rubber band will change with temperature. Method materials procedure diagram. 2 place the first three rubber bands in a room temperature for 10 minutes.
