Elastic Behaviour of Solids

Why gases have two elasticities?

What is the effect of temperature on elasticity?

Which is more elastic, steel or rubber? Why?

Explain elasticity using intermolecular force.

What is the formula of restoring force?

What is intermolecular forces and examples?

A wire is suspended vertically from a rigid support. When loaded with a body in air, the wire extends by $6 \mathrm{mm}$ and when the body is immersed completely in water, the extension is reduced to $4 \mathrm{mm}$. The relative density of material of the body is

Distinguish between elasticity and plasticity.

An uniform steel rod of $5 {\mathrm{mm}}^2$ cross section is heated from $0^{°}C$ to ${25}^{°}C$. Find the force which must be exerted to prevent it from expanding.
$\left({\alpha }_{steel}=12\times {10}^{-6}{/}^{° }C, Y_{steel}=20\times {10}^{10} \mathrm{N}/{\mathrm{m}}^2\right)$

The load versus elongation graph for four wires of the same material is shown in figure. The thinnest wire is represent by the line -

A load $\mathrm{w}$ is suspended from a wire of length $l$ and area of cross-section $A$. Change in length of the wire is $\mathrm{\Delta }l.$ Change in length $\mathrm{\Delta }l$ can be increased to two times by increasing
