Answer 1

The correct answer is Liquid

Key Points

Water shows anomalous behaviour when heated i.e., the amount of water decreases with an increase in temperature from 0°C to 4°C and beyond that, increases with an increase in temperature.
At 12°C, the physical state of water is Liquid. Hence option 1 is correct.
- It is liquid at 25°C also.
The density of water is maximum at 4°C.

Additional Information

At 0°C, the physical state of water is solid or ice because a phase change process takes place at that temperature.
- At 100°C, the physical state of water is gas and that temperature is the boiling point of the water where the water evaporates.
Superionic water is a phase of water that exists at extremely high temperatures.
