true or false question: (Answer format: True, true, true, false) 11. The evaporator is mainly composed of a heating chamber and a separation chamber. 12． When evaporating in split feed mode, the concentrations of each solution obtained are the same. 13. Evaporation is the process in which a solvent is transferred from the liquid phase to the gas phase under the action of heat, so it is a heat and mass transfer process. 14. The main way to improve the evaporation capacity of the evaporator is to increase the heat transfer coefficient. 15. Liquids with higher saturated vapor pressure are more difficult to evaporate.
