What are examples of Thermal expansion?

The area of cross-section of a railway track is $0.01{ \mathrm{m}}^2.$ The temperature variation is $10 °\mathrm{C}.$ Coefficient of linear expansion of material of track is ${10}^{-5} {}^{\circ }\mathrm{C}^{-1}.$ The energy stored per meter in the track is $\mathrm{J} {\mathrm{m}}^{-1}.$ (Young's modulus of material of track is ${10}^{11} \mathrm{N} {\mathrm{m}}^{-2}$)

Rivet is heated before fixing in the hole to join two metal plates.

Look at this table of densities.

Is solid (frozen) pure water more dense or less dense than pure liquid water?

Write the quadrants in which the following points lie:

$\left(-4,7\right)$

Borosilicate glass does not expand much on being heated.

How do plants and animals living inside water in cold regions survive even after the freezing of water?
