Assertion (A) : A beaker filled with water at 4°C overflows if the temperature is decreased or increased.
Reason (R) : Density of water is maximum at 4°C.
Both A and R are true and R is the correct explanation of A
Both A and R are true but R is not a correct explanation of A
A is true but R is false
A is false but R is true
-Water has maximum density at 4°C, so if the water is heated above 4°C or cooled below 4°C density decreases i.e. volume increases. In other words, it expands so it overflows in both the cases.
