Answer:
imagine a balooon filled with air
inside air tries to expand baloon
outside air tries to compress baloon
now if the two pressures are same then the baloon will compress because tension in baloon sheet is going to support outer pressure in reducing area! Thus inner pressure has to be greater to balance both outer pressure and surface tension.
similary you always find if a spherical surface has to be in equilibrium inner pressure had to be more always
or pressure on cocave side has to be more than pressure on covex side...
welll done for asking Y this is so to yourself...
actually that is knowledge
otherwise science becomes general knowledge
