- An air bubble is released at the bottom of a tall jar containing a liquid(Solved)
An air bubble is released at the bottom of a tall jar containing a liquid. The height of the liquid column is 80 cm. The volume of the bubble increases from 0.5 cm3 at the bottom of the liquid to 1.15 cm3 at the top. Figure 11 shows the variation of pressure, P, on the bubble with the reciprocal of volume, $\frac{1}{5}$, as it rises in the liquid.
(i) State the reason why the volume increases as the bubble rises in the liquid column.
(ii) From the graph, determine the pressure on the bubble:
(I) at the bottom of the liquid column;
(II) at the top of liquid column
