Rubber Band Elasticity And Temperature Conclusion

2 place the first three rubber bands in a room temperature for 10 minutes.
Rubber band elasticity and temperature conclusion. 50 m and the increase in length of the rubber band was different dependent on which rubber band was used see table. How does the rubber band feel now. The rubber bands were suspended from a secured pencil and 400g of weight were hung from the pencil. When the rubber bands were removed from their apparatuses a measurement was taken pre stretching.
Anu rajendran lauren janes amanda hermens. Rubber 1 was not as slack as thin and had a smaller circumference than rubber 2. Stretching to the farthest extends of 17 90 o o5 cm 100 c. 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.
Use a spring scale to measure the maximum force that a rubber band can withstand before breaking. Record your data in your notebook. When the rubber bands were attached to the flags the total circumference of the rubber bands then became 0 30 m 0. Effect of temperature on the elasticity of a rubber band table.
One measures the stiffness by changing the force while. Perform multiple trials with rubber bands at different initial temperatures. The hypothesis was supported by our experiment. Results table graph summary of results.
The heated rubber bands were the most elastic. 1 take out rubber band from the box and group them into threes for three trials at each temperature. After 15 minutes remove the shoebox and measure the length of the rubber band again. 3 take one rubber band from the three and cut it at a point.
Five shots with. Now put the shoebox into the refrigerator for 15 minutes. Rubber band elasticity and temperature from science buddies science activities for all ages from science buddies. 40 m and 0.
Elasticity of a rubber band. Introduction background statement of the problem hypothesis. This will be the main temperature for the experiment. Do you think that the force required to break a rubber band will change with temperature.
The effect of temperature on the. This activity brought to you in partnership with science buddies. Method materials procedure diagram. Then measure the length of the rubber band with the ruler.
Allow the rubber band to stretch for three minutes at room temperature. The way to think of the elasticity is in terms of entropy which is basically a measure of disorder. For each temperature we collected data for two colored rubber bands and two natural rubber bands.
