What is the physical state of water at: a) 250ºC b)100ºC ?

At different temperatures, water exists in different physical states:

(a) 25°C: At 25°C, water exists in its liquid state under standard atmospheric pressure. It’s neither frozen nor vaporized, maintaining a liquid form.

(b) 0°C: At 0°C, water undergoes a phase transition from liquid to solid as it freezes. This temperature represents the freezing point of water under standard atmospheric pressure. Water freezes and turns into ice at this temperature.

(c) 100°C: At 100°C, water undergoes a phase transition from liquid to gas, known as boiling. This temperature represents the boiling point of water under standard atmospheric pressure. Water boils and turns into vapor or steam at this temperature.
