Moisture in a solid exerting an equilibrium vapour pressure equal to that of the pure liquid at the same temperature is called the ___________________ moisture ?
Correct answer: A. Unbound
- A. Unbound
- B. Critical
- C. Free
- D. Bound
Explanation
Unbound, or free, moisture has a vapour pressure equal to that of the pure liquid at the same temperature and is relatively easy to remove. Bound moisture has a lower vapour pressure because it is held by the solid.
