What is the physical state of water at
(a) 25°C
(b) 0°C
(c) l00°C?
(a) At 25°C, Water is in the liquid state
(b) At 0°C, Water can exist both in the solid state (ice) and in liquid state. This temperature represents the melting point of ice and freezing point of water
(c) At 100°C, Water can be present both in the liquid and vapor states. This temperature corresponds to the boiling point of water and liquefication temperature of steam.
