Expert Answer

Step 1

The given two processes cab be related based on lowering of freezing point (or melting point) that affects the ice water mixture in equilibrium.

Step 2

(1) The old fashioned cranked ice cream maker using a mixture of ice and rock salt to freeze the ice cream.

Adding salt to ice water lowers freezing point and it helps in freezing of ice cream faster than freezing using pl...
