Which one of the following is used as refrigerant for ice-cream and frozen foods?
- A Dry CO
- B Liquid \(\mathrm{CH}_4\)
- C Dry ice
- D Liquid \(\mathrm{H}_2\)
Answer & Solution
Correct Answer
(C) Dry ice
Step-by-step Solution
Detailed explanation
The most common use of dry ice is to preserve food, using non-cyclic refrigeration. It is frequently used to pack items that must remain cold or frozen such as ice-cream or biological samples, without use of mechanical cooling.
