2 place the first three rubber bands in a room temperature for 10 minutes.
Rubber band elasticity and temperature conclusion.
Five shots with.
3 take one rubber band from the three and cut it at a point.
When the rubber bands were removed from their apparatuses a measurement was taken pre stretching.
The way to think of the elasticity is in terms of entropy which is basically a measure of disorder.
Allow the rubber band to stretch for three minutes at room temperature.
Rubber 1 was not as slack as thin and had a smaller circumference than rubber 2.
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.
Method materials procedure diagram.
The effect of temperature on the.
Then measure the length of the rubber band with the ruler.
Record your data in your notebook.
Elasticity of a rubber band.
Use a spring scale to measure the maximum force that a rubber band can withstand before breaking.
This activity brought to you in partnership with science buddies.
The rubber bands were suspended from a secured pencil and 400g of weight were hung from the pencil.
The hypothesis was supported by our experiment.
The rubber bands in freezing water were the opposite with a stretching length of 9 50 o o5 cm 0 c.
Kimberley answer yes a rubber band will actually become softer or easier to stretch when the temperature gets colder.
One measures the stiffness by changing the force while.
Stretching to the farthest extends of 17 90 o o5 cm 100 c.
50 m and the increase in length of the rubber band was different dependent on which rubber band was used see table.
40 m and 0.
The heated rubber bands were the most elastic.
Perform multiple trials with rubber bands at different initial temperatures.
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.
Effect of temperature on the elasticity of a rubber band table.
Results table graph summary of results.
How does the rubber band feel now.
When the rubber bands were attached to the flags the total circumference of the rubber bands then became 0 30 m 0.
This will be the main temperature for the experiment.
After 15 minutes remove the shoebox and measure the length of the rubber band again.
Do you think that the force required to break a rubber band will change with temperature.
Now put the shoebox into the refrigerator for 15 minutes.
