- Both Statement I and Statement II are true
- Both Statement I and Statement II are false
- Statement I is true but Statement II is false
- Statement I is false but Statement II is true
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Freezing methods differ in their rates and applicability.
Cryogenic and fluidized-bed freezing have specific characteristics.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand different freezing methods.
Step 3: Detailed Explanation:
Statement I: Cryogenic freezing has a much greater rate than liquid-immersion freezing - true.
Cryogenic freezing uses liquid nitrogen or CO\(_2\) for very rapid freezing.
Statement II: Large or non-uniform products can be subjected to fluidized-bed freezing - false.
Fluidized-bed freezing is suitable for small, uniform, free-flowing products.
Large or non-uniform products are not suitable.
Thus, Statement I is true, but Statement II is false.
Step 4: Final Answer:
Statement I is true but Statement II is false.
Hence, the correct option is (C).
