In food process engineering, the unsteady state of conductive heat transfer states that
In food process engineering, the unsteady state of conductive heat transfer states that
Show Hint
Unsteady-state heat transfer is crucial in food processing, as it determines how heat moves through food materials over time.

- The changes in temperature depend only on the position
- The changes in temperature depend not only on the position but also on the time
- No changes in temperature
- The changes in temperature depend only on the time
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In unsteady-state conductive heat transfer, the temperature changes depend both on the position within the material and the time, making it a dynamic process.
