Elasticity of a rubber band.
Rubber band elasticity and temperature conclusion.
The effect of temperature on the.
How does the rubber band feel now.
Perform multiple trials with rubber bands at different initial temperatures.
This activity brought to you in partnership with science buddies.
1 take out rubber band from the box and group them into threes for three trials at each temperature.
Do you think that the force required to break a rubber band will change with temperature.
Method materials procedure diagram.
The hypothesis was supported by our experiment.
This will be the main temperature for the experiment.
Then measure the length of the rubber band with the ruler.

The way to think of the elasticity is in terms of entropy which is basically a measure of disorder.
40 m and 0.
When the rubber bands were attached to the flags the total circumference of the rubber bands then became 0 30 m 0.
When the rubber bands were removed from their apparatuses a measurement was taken pre stretching.
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.
Results table graph summary of results.
For each temperature we collected data for two colored rubber bands and two natural rubber bands.
Allow the rubber band to stretch for three minutes at room temperature.
Use a spring scale to measure the maximum force that a rubber band can withstand before breaking.
The heated rubber bands were the most elastic.
Record your data in your notebook.
Rubber 1 was not as slack as thin and had a smaller circumference than rubber 2.
The rubber bands were suspended from a secured pencil and 400g of weight were hung from the pencil.
The rubber bands in freezing water were the opposite with a stretching length of 9 50 o o5 cm 0 c.
Five shots with.
Stretching to the farthest extends of 17 90 o o5 cm 100 c.
2 place the first three rubber bands in a room temperature for 10 minutes.
50 m and the increase in length of the rubber band was different dependent on which rubber band was used see table.
Does cold temperature affect the elasticity of a rubber band.
Introduction background statement of the problem hypothesis.
Effect of temperature on the elasticity of a rubber band table.
Kimberley answer yes a rubber band will actually become softer or easier to stretch when the temperature gets colder.
Now put the shoebox into the refrigerator for 15 minutes.
One measures the stiffness by changing the force while.
