Question

Unfreezing two practical used_______

Answer 1

Two practical applications of freezing action are freezing point depression to remove ice and freeze-drying of foods.

Step-by-step explanation:

In the context of freezing action, two practical applications are:

1. Freezing point depression to remove ice from roadways and aircraft control surfaces. This process exploits the fact that adding certain substances can lower the freezing point of water, making it easier to remove ice.
2. Freeze-drying of foods. In this process, the food is frozen and then placed in a vacuum. The low pressure in the vacuum allows for rapid dehydration of the frozen food, preventing the formation of ice crystals.
