It depends. If the temperature is a constant temperature similar to Earth's, the liquid would appear like a ball of floating liquid, similar to the liquid-metal mercury on Earth.

If the temperature is hot, the liquid will evaporate into space steam.
Earth is the only planet in our solar system with an abundance of liquid water on its surface. Other planets may have water in the form of ice or vapor, but not in liquid form like Earth.
