Explain why the aquatic species are more conmfortable in cold water during winter season rather than warm water during the summer.

Explanation

Total pressure `= 1 atm`
`P_(N2)=((80)/(100)) xx` Total pressure `= (80)/(100) xx 1 atm = 0.8 atm`
` P _(O2)= ((20)/(100)) xx 1 = 0.2 atm`
According to Henry.s Law
`P_("solute" ) = K _(H) x _("solute in solution") `
`therefore P _(N2) = (K _(H))_("Nitrogen") xx` Mole fraction of Nitrogen in solution
`(0.8)/(8.5 xx 10 ^(4)) = x _(N_(2))`
`x _(N2)=9.4 xx 10 ^(-6)`
Similarly `x _(O2)= (0.2)/( 4.6 xx 10 ^(4)) = 4.3 xx 10 ^(-6)`
