Rubber elasticity refers to a property of crosslinked rubber.
Rubber band elasticity and temperature experiment results.
Then measure the length of the rubber band within the marks just drawn.
Tie one end of the rubber band to the middle of the skewer and the other end to the hook or knob on the steel weight.
Gently being careful not to burn yourself on the hot water or steam lower the weight and rubber band into the graduated cylinder.
This can be repeated many times with no apparent degradation to the rubber.

The heated rubber bands 130 degrees fahrenheit sustained an average force of only 25 5n and stretched to an average 69 35cm.
Place the rubber band flat on a table and mark two lines from where the rubber band s elasticity will be measured.
The room temperature rubber bands 66 degrees fahrenheit broke at an average force of 30 2n.
Results the frozen rubber bands 0 degrees fahrenheit broke at the average force of 33 6 newtons and stretched to 52cm.
Introduction background statement of the problem hypothesis.
This will be the main temperature for the experiment.
It can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length.
2 place the first three rubber bands in a room temperature for 10 minutes.
