List of top Physics Questions on Pressure asked in KEAM

The compressibility of water is $ 6\times {{10}^{-10}}{{N}^{-1}}{{m}^{2}} $ . If one litre is subjected to a pressure of $ 4\times {{10}^{7}}N{{m}^{-2}}, $ the decrease in its volume is

Two spherical soap bubbles of diameters 10 cm and 6 cm are formed, one at each end of a narrow horizontal glass tube. If the surface tension of the soap solution is 0.03 Nm$^{-1}$, then the pressure difference in pascal between the two ends of the tube is
