Stretching to the farthest extends of 17 90 o o5 cm 100 c.
Rubber band elasticity and temperature conclusion.
Introduction background statement of the problem hypothesis.
The rubber bands in freezing water were the opposite with a stretching length of 9 50 o o5 cm 0 c.
Record your data in your notebook.
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.

Rubber band elasticity and temperature from science buddies science activities for all ages from science buddies.
Do you think that the force required to break a rubber band will change with temperature.
For each temperature we collected data for two colored rubber bands and two natural rubber bands.
1 take out rubber band from the box and group them into threes for three trials at each temperature.
50 m and the increase in length of the rubber band was different dependent on which rubber band was used see table.
The rubber bands were suspended from a secured pencil and 400g of weight were hung from the pencil.
Kimberley answer yes a rubber band will actually become softer or easier to stretch when the temperature gets colder.
This will be the main temperature for the experiment.
One measures the stiffness by changing the force while.
After 15 minutes remove the shoebox and measure the length of the rubber band again.
The hypothesis was supported by our experiment.
3 take one rubber band from the three and cut it at a point.
This activity brought to you in partnership with science buddies.
Now put the shoebox into the refrigerator for 15 minutes.
Perform multiple trials with rubber bands at different initial temperatures.
When the rubber bands were removed from their apparatuses a measurement was taken pre stretching.
2 place the first three rubber bands in a room temperature for 10 minutes.
40 m and 0.
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.
Effect of temperature on the elasticity of a rubber band table.
Then measure the length of the rubber band with the ruler.
Results table graph summary of results.
How does the rubber band feel now.
The effect of temperature on the.
When the rubber bands were attached to the flags the total circumference of the rubber bands then became 0 30 m 0.
Rubber 1 was not as slack as thin and had a smaller circumference than rubber 2.
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.
Does cold temperature affect the elasticity of a rubber band.
