Given below are two statements :

Statement (I): NaCl is added to the ice at 0°C, present in the ice cream box to prevent the melting of ice cream.

Statement (II): On addition of NaCl to ice at 0°C, there is a depression in freezing point.

In the light of the above statements, choose the correct answer from the options given below :

<p>Statement I : Correct</p> <p>NaCl addition to ice causes preventing the melting of ice. On adding NaCl to ice, freezing point lowers. This creates a colder mixture, preventing the ice cream from melting.</p> <p>Melting point of ice is 0$^\circ$C. When only ice is used to make ice cream, at 0$^\circ$C ice starts melting by absorbing the energy from its environment in the form of heat. Addition of salt to ice while making the cream lowers the freezing point of the ice, allowing it to reach a colder temperature and thus the ice cream mixture freezes properly, So, the salt causes ice to melt at a lower temperature than pure ice.</p> <p>Statement II : Correct</p> <p>Decrease in freezing point while addition of NaCl to ice at 0$^\circ$C is due to the colligative property depression in freezing point.</p> <p>So, both the statements are correct.</p> <p>Both statement I and statement II are true.</p>
