Final answer:
At 25°C and 1 atm on Earth, water is in the liquid state.
Step-by-step explanation:
Water, at 25°C and 1 atm on Earth, would be in the liquid state. At this temperature and pressure, water exists as a liquid because it is above its freezing point but below its boiling point. In the liquid state, water molecules have enough energy to move around and flow, but they are still close together and experience intermolecular forces that hold them together.
