Rubber bands increase in size when soaked in kerosene due to the absorption of the petroleum-based solvent by the rubber material, causing it to swell. This absorption leads to an expansion in the volume of the rubber band as it accommodates the kerosene molecules.

Why can kerosene expand a rubber band?
Kerosene can expand a rubber band by dissolving the rubber, causing it to swell. This is because kerosene can penetrate the rubber's molecular structure, disrupting the interactions between the rubber molecules and causing it to stretch and expand.
What is a good hypothesis for the question how will the stretch of the rubber band effect the potential energy created?
A good hypothesis could be: "I hypothesize that as the rubber band is stretched further, the potential energy stored in the rubber band will increase. This is because stretching the rubber band further will increase the tension and displacement, resulting in a greater potential energy stored in the system."
What happens to the molecules in a rubber band when tension is applied?
When tension is applied to a rubber band, the molecules in the rubber band are stretched apart, resulting in an increase in the overall length of the rubber band. This stretching occurs because the tension causes the molecules to pull away from each other, storing potential energy in the rubber band.
What is one way you can increase the elastic potential energy of a rubber band?
You can increase the elastic potential energy of a rubber band by stretching it further from its natural length. This will cause the rubber band to store more potential energy as elastic potential energy increases with the amount of stretch applied.
What would happen to a rubber band if weight is added to it?
If weight is added to a rubber band, it will stretch and elongate. The amount of stretch will depend on the elasticity and strength of the rubber band. Eventually, if too much weight is added, the rubber band may break.
Why does a rubber band increase in size when placed in kerosene?
Rubber is a hydrophobic material and tends to swell when in contact with non-polar solvents like kerosene. This is because the non-polar solvent disrupts the intermolecular forces within the rubber, causing it to expand.
Why can kerosene expand a rubber band?
Kerosene can expand a rubber band by dissolving the rubber, causing it to swell. This is because kerosene can penetrate the rubber's molecular structure, disrupting the interactions between the rubber molecules and causing it to stretch and expand.
What would you need to do to a rubber band to increase its elastic potential energy?
Stretch the rubber band.

What is an example of stretching a rubber band?
One example of stretching a rubber band is pulling it from both ends to increase its length and storing potential energy in the process.
Is there a change in the sound produced when you plucked the rubber band while stretching?
Yes, the sound produced when you pluck a rubber band while stretching it will change. As you stretch the rubber band, you increase the tension on it, causing the frequency of vibrations to increase and resulting in a higher-pitched sound. Conversely, releasing the tension will lower the pitch of the sound produced.
How do you remove melted rubber band from cloth?
To remove melted rubber band from cloth, you can place the cloth in the freezer to harden the rubber, then scrape it off with a blunt object like a butter knife. Alternatively, use a cloth soaked in hot vinegar to soften the rubber before gently scraping it off. Wash the cloth with detergent afterwards to remove any residue.
How does changing the length of the rubber band affect the sound?
Changing the length of the rubber band can affect the pitch of the sound produced. Shortening the rubber band tends to increase the pitch, while lengthening it lowers the pitch. This is because the shorter length creates higher frequency vibrations and vice versa.
