Mass Transfer During constant rate period, the rate of drying decreases with the Decrease in air temperature Increase in air humidity Both A & B Neither A nor B Decrease in air temperature Increase in air humidity Both A & B Neither A nor B ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that The system comprises of miscible liquids The system comprises of an azeotrope On heating, a vapor phase will appear ; while on cooling, a solid phase will appear The system comprises of partially mis-cible liquids The system comprises of miscible liquids The system comprises of an azeotrope On heating, a vapor phase will appear ; while on cooling, a solid phase will appear The system comprises of partially mis-cible liquids ANSWER DOWNLOAD EXAMIANS APP
