A flask of volume $10^3\ cc$ is completely filled with mercury at $0\,^oC$. The coefficient of cubical expansion of mercury is $180 \times 10^{-6}/^oC$ and that of glass is $40 \times 10^{-6}/^oC$. If the flask is now placed in boiling water at $100\,^oC$, ........ $cc$ mercury will overflow

If mass-energy equivalence is taken into account, when water is cooled to from ice. The mass of water should

A pendulum clock keeps correct time at $0\ ^oC$. The thermal coefficient of linear expansion of the  material of the pendulum is $\alpha$. If the temperature rises to $t\ ^oC$, then the clock loses per day by (in second)

A bimetallic strip consists of metals $X$  and $Y.$  It is mounted rigidly at the base as shown in the figure. The metal $X$  has a higher coefficient of expansion as compared to that for metal $Y.$  When the bimetallic strip is placed in a cold bath ?

Heat required to melt $1\,gm$ of ice is $80\, cal$. A man melts $60\, gm$ of ice by chewing it in one minute, his power is ........ $W$

A clock which keeps correct time at $20\,^oC$ has a pendulum rod made of brass. How many seconds will it gain or lose per day when temperature falls to $0\,^oC$ ? $(\alpha = 18\times10^{-6}/^oC)$
