NEET Physics Question - Thermal Physics - Heat Transfer

Assertion (A): Salt is mixed with ice in an ice-cream box.

Reason (R): Salt lowers the temperature of ice.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Adding salt to ice creates a freezing mixture by lowering the freezing point of water (freezing point depression), allowing temperatures well below \(0^{\circ}\text{C}\). Both A and R are true, and R explains A.
