What About A Rubber Band Can It Change Its Shape On Stretching

Table of Contents

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.

Can rubber band change its shape?

Yes, an elastic band can change its shape when a force is applied thereto and may regain its shape when the force is removed. It is solid in nature but upon the appliance of force, the form can change thanks to the elastic nature of the elastic band.

What change occurs when a rubber band stretches?

Answer: Stretching a rubber band is a physical change because the size of the rubber band changes. The color of the rubber band sometimes can change as well when it is stretched. However, the material that the rubber band is made of does not change.

What about a rubber band can it change its shape on stretching is it a solid B What about sugar and salt when kept in different jars These take the shape of the jar are they solid C What about a sponge it is a solid yet we are able to compress it why?

Answer: A rubber band changes shape under force and regains the same shape when the force is removed. Therefore, it is considered as a solid.

Is rubber band a solid give reasons?

Can you change the shape of plastic ruler?

A plastic ruler can be bent by using force. Its shape changes. However, when too much force is applied, the plastic ruler breaks into two.

How can you change the size of a rubber band?

Although rubber bands seem to never lose their shape or elasticity, you can shrink them by applying heat.

What happens when we stretch the rubber bands will it become longer or shorter Why?

As the rubber is stretched the bonds between adjacent chains are broken. Stretching a rubber band makes it get hot – heat energy is lost. Therefore if you put heat energy into a rubber band it will get shorter – unlike most materials when they are heated.

What information would you use to show that stretching of a rubber band is a reversible change?

Explanation: If we stretch a rubber band with force of our hands, it undergoes a change and its length increases. But, on releasing the force, the rubber band comes back to its original length. So, the stretching of rubber band is a reversible change, the stretching of a spring is also a reversible change.

Is Sponge a true solid?

The sponge is matter and considered as solid because it has a definite volume and shape does not change unless compressed. A sponge can be compressed easily even though it can be considered as solids because they have minute pores in it which are filled with air.

Is sugar and salt solid?

Sugar and salt are both solids. They take the shape of their respective jars as the individual crystals of each are small and many of these small sugar or salt crystals can fill up the empty spaces of a container.

Can matter change its state?

It can definitely change its shape, size, and volume. For examples, water turns into ice upon freezing, here the form of water converts from the liquid state into the solid state; the matter itself doesn’t change but it transforms its shape. Evaporation changes the form of water from liquid state to gaseous state.

Which type of solid is rubber?

Unlike a crystalline solid, an amorphous solid is a solid that lacks an ordered internal structure. Some examples of amorphous solids include rubber, plastic, and gels.

Is the rubber band solid justify your answer?

A rubber band can change its shape on stretching , will you classify it as solid or not ? Justify your answer. Yes, it can be classified as a solid. It is an elastic solid which changes its shape on stretching and regains the same when the stretching force is removed.

Is rubber band an amorphous solid?

Examples of amorphous solids include glass, rubber, and plastics. The physical properties of amorphous solids differ from those of crystalline solids.

Why does a plastic ruler keep its shape?

On the other hand, plastic materials exhibit much more elastic deformation, but the amount of plastic deformation is small, meaning that they break rather than yield. In the case of your rulers, you’ve probably bent your ruler past the point where it will regain its shape, so it stays bent.

Why can we bend ruler?

The ruler is much thicker along its breadth than height so you are bending much more material. Same force is trying to bend about 20 times as much material. A bending force that will easily bend a ruler through its height will cause a very very slight bend along its breadth. Try it.

How can you change the shape of Cartolina strip?

Answer Noodles – We can easily change the shape of the noodles by boiling or cooking the dry noodles. Chocolate bar – We can easily change the shape of a chocolate bar bar melting the chocolate and reshaping it in the necessary shape.

Does rubber shrink when heated?

The rubber band actually expands when it gets colder! This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.

How do you make a rubber band tighter?

1 Method 1 of 2: Shrinking Rubber Using Hot Water Run hot water over the rubber. At first, try using tap water. Place the rubber in boiling water if hot tap water fails to shrink the rubber. The high heat will force the rubber to shrink if you allow it to boil for 5 to 10 minutes. Bend the rubber into shape.

Is stretching a rubber band a physical or chemical change?

Stretching a rubber band is a physical change because the size of the rubber band changes. The color of the rubber band sometimes can change as well when it is stretched. However, the material that the rubber band is made of does not change. The rubber band is still rubber.
