the solution shows positive deviation.
so ΔH > 0
so the process is endothermic.
hence the solution absorbs heat and hence cools down
when we mix solute in solvent to prepare a non ideal solution showing +ve deviation the solution becomes
(1)hot
(2)cold
(3)may become cold or may be hot
(4)none of these
answer with explanation
the solution shows positive deviation.
so ΔH > 0
so the process is endothermic.
hence the solution absorbs heat and hence cools down
in non ideal sol showing + deviation .........some energy is lost in breaking H bonds between solvent molecules.......so solution becomes cold...............
