If the water level in the dish remains unchanged from one day to the next, it suggests that the rates of evaporation and condensation are in equilibrium.
The rates of evaporation and condensation appear to be in balance if the water level in the dish doesn't change from day to day. Stated differently, the quantity of water that evaporates from the dish is equivalent to the quantity of water that condenses back into the dish.
When the processes of evaporation and condensation are balanced and there is no net change in the water level over time, the state is known as a dynamic equilibrium.
