Steam at $100\,^oC$ is more dangerous than the same mass of water at $100\,^oC$ because the steam
moves faster
is less dense
contains more heat
has a higher specific heat capacity
The value of coefficient of volume expansion of glycerin is $5 \times 10^{-4}\, K^{-1}$. The fractional change in the density of glycerin for a rise of $40\,^oC$ in its temperature, is
Heat required to melt $1\, gm$ of ice is $80\, cal$. A man melts $60\, gm$ of ice by chewing in one minute. His power is ........ $W$
A glass flask of volume one litre at $0\,^oC$ is filled, level full of mercury at this temperature. The flask and mercury are now heated to $100\,^oC$. How much mercury will spill out, if coefficient of volume expansion of mercury is $1.82 \times 10^{-4}/^oC$ and linear expansion of glass is $0.1 \times 10^{-4}/^oC$ ? ............ $\mathrm{cc}$
