Size numbers Generally, rubber bands are numbered from smallest to largest, width first. Thus, rubber bands numbered 8–19 are all ​1⁄16 inch wide, with lengths going from ​7⁄8 inch to ​3 1⁄2 inches. Rubber band numbers 30–35 are for width of ​1⁄8 inch, going again from shorter to longer.

If you pluck a rubber band, the rubber band moving back and forth produces twanging sounds. Sound travels when a string vibrates, it makes molecules of gases in the air next to it vibrate. The molecules squeeze together, then spread apart. A vibration that spreads away from a vibrating object is a sound wave.

A rubber band can change its shape on stretching but it is a solid. This happens because pressure is applied on the band which makes it to change the shape and it gains its original shape when released. So, its a solid.

A rubber band is considered a solid because it changes shape under the action of force and when the force is removed, it regains its original shape.

amorphous solids

Rubber band is solid. On applying force a solid may change its shape as in case of rubber band. But as soon as the force is removed, it comes back to its original shape. Rubber bands are solid because they their molecules are close to one another and perfectly sets in the definition of solids.

The rubber band is considered as solid because as we apply force and stretch the rubber band it changes its shape and gets elongated but after releasing the force, it moves back to its original shape. This property of rubber is known as elasticity.

Yes rubber band is a solid. But it changes its shape under force and regains the same shape when the force is removed. If excessive force applies, it breaks. So, according to this property , it is a solid.

Rubber (or natural rubber, anyways), is obtained as a sap (latex) from the rubber tree ( Hevea Brasiliensis ), In this form, the unprocessed rubber is definitely a liquid.

One of the easiest ways to make a substitute for rubber, or a type of putty, is to mix together corn starch, water and glue. When you add vinegar to the recipe, it causes the rubber to become too watery. Store unused portions of the cornstarch and water in the refrigerator.

Rubber is a natural product produced by plants and is present in many of the goods used in our daily lives. It still plays an important role, and that is why we need to search for new rubber sources. Nowadays, 99% of the natural rubber we use is extracted from a tree called Hevea brasiliensis.

Because rubber is strong, flexible, and a very poor conductor of heat and electricity, it’s often used as a strong, thin, jacketing material for electrical cables, fiber-optic cables, and heat pipes.

Material Substitutes for Rubber

• Silicone. Silicone is a good substitute for rubber.
• Nitrile. Nitrile butadiene rubber (NBR) is a suitable natural rubber substitute because it is stable in a variety of temperatures.
• Vinyl. First created in 1920, vinyl is another man-made substitute for rubber.
