Will the hot weather evaporate?

The greater the concentration of alcohol, the easier it is to volatilize. At a certain temperature, the gas phase and liquid phase did not reach the balance of vapor evaporation and liquid phase condensation at first, and the ethanol molecules on the liquid surface evaporated to the gas phase. When evaporation and condensation reach equilibrium, the concentration of ethanol in gas phase and liquid phase remains unchanged. According to Raoul's law of solution, the vapor partial pressure of ethanol in the gas phase is directly proportional to its concentration in the liquid phase, so the greater the ethanol concentration, the greater the ethanol partial pressure, that is, the easier it is to evaporate.

Alcohol will volatilize, and the volatilization speed is much faster than that of water, so the taste of wine stored for a long time will of course be poor, and the degree will be reduced accordingly. There are certain requirements for the storage of wine. If it is well sealed, the liquor will not go bad for a long time, and the wine is old and fragrant, and the more it is put, the better it tastes. If the seal is not good, the alcohol will volatilize and the degree will be reduced accordingly.
