Which of the following statements about drying rate are correct? Statement 1: It depends on vapor pressure of water at drying temperature. Statement 2: It depends on humidity in the external atmosphere.

Which of the following statements about drying rate are correct? Statement 1: It depends on vapor pressure of water at drying temperature. Statement 2: It depends on humidity in the external atmosphere. Correct Answer True, False

Rate of drying depends on the equilibrium vapor pressure of water present in the food. It also depends on the moisture of the food. Vapor pressure of water at drying temperature plays a major role in drying rate. It depends on the vapor pressure in the external environment.
