Pls the answer here is B
Water at 0° has higher volume than at 4°... Minimum volume at 4° and maximum volume at 0°
Anomalous expansion of water
pure water boils at a definite temperature
water does not boil at a definite temperature only pure water does that
Which of the following statements about water is NOT correct?
A. Pure water freezes at 0°C under normal pressure
B. The volume of a given mass of water at 0° is less than its volume at 4°C
C. Water boils at a definite temperature
D. Water evaporates at all temperatures
E. Water has its maximum density at 4°C
The selected option is wrong. Because Water evaporates at all tempratures, the correct answer is E. Because water has it's least volume at 4C, hence it also has it's maximum density at 4C
The correct option is B
When water is heated from 0°C to 4°C, its volume decrease (Anomalous behaviour of water)
Hence, water has minimum volume 4°C and maximum density of 4°C (Density varies inversely as Volume)
Exactly
The volume of water is at first maximum at 0°c and decreases depreciably till it gets minimum at 4°c
This is known as Anomalous Behavior of Water
Also,you will recollect that Volume id inversely proportional to Density
As such,water tends to get its maximum Density at 4°c
