Question

water exists in liquid state over a wide range of temperature 0 degree Celsius to 100 degree c
give reason

Answer 1

Under normal atmospheric conditions, boiling temperature of water is 100 degree C. The types of molecules of the  water  affects the boiling point. The force of attraction between the molecules is relatively strong, hence boiling point is  higher.  Similarly the freezing  point is 0 degree C. During these condition water remains in liquid state. However, the pressure and impurities in water can cause in variation of both boiling point and freezing point of water. 

Answer 2

Answer:

Water remains in liquid state between 0°C and 100°C.
