A liquid of specific gravity \( 1.5 \) is observed to rise \( 3.0 \mathrm{~cm} \) in a capillary tube of diameter \( 0.50 \mathrm{~mm} \) and the liquid wets the surface of the tube. Calculate the excess pressure inside a spherical bubble of \( 1.0 \mathrm{~cm} \) diameter blown from the same liquid. Angle of contact \( =0^{\circ} \).
