Is the air in a closed container at 100% relative humidity?

Imagine a sealed container filled with any amount of liquid water at any constant temperature and pressure where water can be liquid. Is the air in the container necessarily at 100% relative humidity?

At equilibrium, I’d say yes.

I agree.

Due to temperature fluctuations it will not always be at 100%, but at equilibrium it will be.
