When salt is added to water, the boiling point increases and the freezing point decreases. This phenomenon is due to the colligative properties of solutions, where the presence of a solute affects the boiling and freezing points of the solvent.
In an adiabatic change, no heat is exchanged with the surroundings, so heat remains unchanged. However, the temperature of the system can change due to work done on or by the system.
The rate of evaporation for a certain liquid depends on all the above factors. It depends on the temperature of the liquid, the temperature of the air, and the open surface area of the liquid.
It will take more time to cook rice on Mount Everest due to the lower atmospheric pressure at high altitudes, which lowers the boiling point of water. This means water boils at a temperature below 100°C, slowing the cooking process.
