What is the physical state of water at:
(a) 250C (b) 00C (c) 1000C
(a) Between 00C and 1000C water exists as a liquid. The physical state of water at 25°C is liquid.
(b) 0°C is the melting point of ice as well as the freezing point of water. Hence, the physical state of water can be both liquid and solid at 0°C.
(c) 1000C is the boiling point of water as well as the condensation temperature of steam. Hence, the physical state of water can be both liquid or gas at 1000C.
