$A$ pressure of $1 \,mm$ of mercury is equivalent to

The pressure at the bottom of a tank containing a liquid does not depend on

Why does an air bubble formed in water grow in size as it rises from the bottom to the surface? Explain.

$A$ bubble of volume $V_0$ is released from a depth $h$ in a lake. If the atmospheric pressure is $P$ and the temperature is assumed to be constant,what is the new volume of the bubble when it reaches the surface? (Density of water is $\rho$)

$A$ swimming pool has a depth of $3 \,m$. The pressure at the bottom of the pool due to water alone is: (Density of water is $1000 \,kg \,m^{-3}$, Acceleration due to gravity $= 10 \,m \,s^{-2}$)

Describe the Torricelli experiment for the measurement of atmospheric pressure.
