1.	(i) Explain why the aquatic species are more comfortable in cold water during water season rather than warm water during the summber? (ii) What is osmosis?
Answer» <P> Solution :(i) Total pressure=1 atm `P_(N_(2))=((80)/(100))xx"Total pressure"=(80)/(100)xx1atm=0.8atm` `P_(O_(2))=((20)/(100))xx1=0.2atm` According to Henry.s Law `P_("SOLUTE")=K_(H)x_("solute in solution")` `therefore P_(N_(2))=(K_(H))_("Nitrogen")xx`Mole fraction of Nitrogen solution `(0.8)/(8.5xx10^(4))=x_(N_(2))` `x_(N_(2))=9.4xx10^(-6)` similarly `x_(O_(2))=(0.2)/(4.6xx10^(4))=4.3xx10^(-6)` (ii) Osmosis is a spontaneous process by which the SOLVENT MOLECULES pass through a semipermeable membrane from a solution of lower concentration to the solution of higher concentration.
