Question: Why Is Rubber So Elastic?

Why glass is more elastic than rubber?

(a) Glass is more elastic than rubber because for a given applied force per unit area, the strain produced in glass is much smaller than the strain produced in rubber..

Why is steel elastic than rubber?

So, it can be said that for a given amount of stress, the strain produced in the steel is comparatively smaller than the strain produced in the rubber. Therefore, with the help of Young’s modulus, it can be concluded that steel has greater elasticity than rubber.

Is Rubber perfectly elastic?

Rubber is a common visco-elastic material which means it is both viscous and elastic. Further, Rubber is also characterized by another property called resilience. Resilience is the ability of a material to absorb energy when it is deformed elastically, and release that energy upon unloading.

Which is the most elastic?

rubberElasticity is the ability of a material to regain its own original shape after being stretched according to which, rubber is the most elastic substance.

Is rubber worse than plastic?

Is rubber better than plastic for the environment? Neither rubber is more harmful than plastic nor is vice-versa. If you ask an environmentalist, he or she will say that both rubber and plastic are dangerous. Both when burned cause an emission of toxic gases or we can say poisonous fumes.

Which is more elastic Mcq?

Air is more elastic than water.

Is rubber elastic or inelastic?

It is this constant jostling that produces a resisting (elastic) force in the chains as they are forced to become straight. While stretching a rubber sample is the most common example of elasticity, it also occurs when rubber is compressed.

Is rubber more elastic than iron?

Since, the iron rod regains its original configuration more efficiently than rubber, it is iron which is more elastic than rubber. … However, the iron rod is less plastic because it shows more tendency to return to its original configuration after the deforming forces are removed.

Is rubber harder than plastic?

Rubber MIGHT specifically refer to cis-polyisoprene (natural rubber), which is one specific example of one of those polymers I mentioned. … But, most likely, a rubber (common usage) is a stretchy, bouncy polymer while a plastic (common usage) is a hard, firm one.

How do you make rubber less elastic?

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

Is rubber better than plastic?

A polymer, Rubber is a material that is either acquired through natural means i.e. rubber plants or by using petroleum oil whereas A polymer, Plastic is a material that has the power to be shaped and formed by the appliance of warmth and pressure. … In terms of toxicity, rubber is more toxic than plastic.

Does rubber have plastic?

Both these compounds are polymer materials. … The main difference between plastic and rubber is that plastic is essentially a synthetic polymer whereas rubber can be found as a natural polymer or can be produced as a synthetic polymer.

Why steal is more elastic than rubber?

The strain produced in rubber is much larger compared to that in steel. This means that steel has a larger value of Young’s modulus of elasticity and hence, steel has more elasticity than rubber. … Rubber gets stretched because there is strain produced in it when stress is applied.

Is rubber a ductile material?
