Phloem loading and unloading process are respectively

Pay load is defined as the difference between the mass of displaced air and the mass of the balloon Calculate the pay-load when a balloon of radius 10m mass 100 kg is filled with helium at 1.66 bar at 27^(@)C (Density of air = 1.2 kg m^(-3) and R = 0.083 bar dm 3 K^(-1) mol^(-1) ) .

The process of loading at the source produces a hypertonic condition in the phloem.
