MediumThe top of a lake gets frozen at a place where the surrounding air is at a temperature of $-20\,^oC$. Then
- AThe temperature of the layer of water in contact with the lower surface of the ice block will be at $0\,^oC$ and that at the bottom of the lake will be $4\,^oC$
- BThe temperature of water below the lower surface of ice will be $4\,^oC$ right up to the bottom of the lake
- CThe temperature of the water below the lower surface of ice will be $0\,^oC$ right up to the bottom of the lake
- DThe temperature of the layer of water immediately in contact with the lower surface of ice will be about $-20\,^oC$ and that of water at the bottom will be $0\,^oC$

View SolutionFind the difference in temperature between the water at the top and the bottom of a $20 \ m$ high waterfall, assuming $10 \%$ of the energy of the fall is spent in heating the water. [Use specific heat capacity of water $= 4000 \ J \ kg^{-1} K^{-1}$ and $g = 10 \ m/s^2$]. (in $^{\circ} C$)
Water falls from a height of $210 \, m$. Assuming the whole of the energy due to the fall is converted into heat,the rise in temperature of water would be .......... $^\circ C$ $(J = 4.3 \, J/cal)$.

View Solution$A$ metal block is made from a mixture of $2.4 \ kg$ of aluminium,$1.6 \ kg$ of brass,and $0.8 \ kg$ of copper. The metal block is initially at $20^{\circ} C$. If the heat supplied to the metal block is $44.4 \ cal$,find the final temperature of the block if the specific heats of aluminium,brass,and copper are $0.216, 0.0917, 0.0931 \ cal \cdot kg^{-1} \cdot ^{\circ}C^{-1}$ respectively.
