We are able to squeeze snow and make balls out of it because of

A

anomalous behaviour of water

B

large latent heat of ice

C

large specific heat of water

D

low melting point of ice

(KVPY-2009)

Solution

(a)

When we exert pressure on snow, solid snow melts into liquid, to get lesser space. It happens due to anomalous behaviour of water as water is less dense in solid form than liquid form i.e. water covers less space in liquid form than solid. When we loose our grip on snow (releases the pressure) this melted snow, refreezes again thus fusing the snow crystal.

Thus all this happens due to anomalous behaviour of water.

A unit scale is to be prepared whose length does not change with temperature and remains $20\,cm$, using a bimetallic strip made of brass and iron each of different length. The length of both components would change in such a way that difference between their lengths remains constant. If length of brass is $40\,cm$ and length of iron will be$…cm$

$\left(\alpha_{\text {iron }}=1.2 \times 10^{-5} K ^{-1}\right.$ and $\left.\alpha_{\text {brass }}=1.8 \times 10^{-5} K ^{-1}\right)$.
