Drying of a solid involves _________________ transfer ?
Correct answer: B. Both heat and mass
- A. Only heat
- B. Both heat and mass
- C. Only mass
- D. None of these
Explanation
Drying requires heat to vaporize moisture and mass transfer to move that vapour from the solid surface into the surrounding gas. Omitting either transfer process would prevent drying.
