Vedclass · Answer

(A) The correct answer is $(a)$. When hot water is placed in a freezer,it loses heat to the surroundings and its temperature decreases until it reaches $0\,^{\circ}	ext{C}$. At $0\,^{\circ}	ext{C}$,the water begins to undergo a phase change from liquid to solid (ice). During this phase transition,the temperature remains constant at $0\,^{\circ}	ext{C}$ because the heat being removed is used as latent heat of fusion. Once all the water has frozen into ice,the temperature of the ice will continue to decrease further below $0\,^{\circ}	ext{C}$ as it continues to lose heat to the freezer environment. Graph $(a)$ correctly depicts this cooling curve: a steady decrease,a horizontal plateau at $0\,^{\circ}	ext{C}$ during freezing,and a further decrease after the phase change is complete.
