Vedclass · Answer

(A) The density of water is maximum at $4^{\circ}C$,which means the volume of water is minimum at $4^{\circ}C$. As the temperature increases from $1^{\circ}C$ to $4^{\circ}C$,the volume of water decreases,causing the molarity $(M = n/V)$ to increase. As the temperature increases from $4^{\circ}C$ to $25^{\circ}C$,the volume of water increases due to thermal expansion,causing the molarity to decrease. Therefore,the molarity first increases and then decreases,which is represented by plot $A$.
