It depends upon the nature of material.For example if the light falls on water which is liquid most of the light get transmitted and little amount of light gets reflected by the water surface.In some substance absorption of light also takes place but this absorption is possible only when the frequency of the light is complementary to the frequency otherwise it gets reflected or transmitted.For example, leaves contain chlorophyll, which absorbs the blue and red colour of the spectrum and reflects the green therefore leaves appear green.Therefore its the nature of liquid and gas which decides whether light gets refracted, reflected  or absorbed.
