A beaker is filled completely with water at 4^ C . Identify the incorrect statement.
Options
- AWater overflows when heated above 4^ C .
- BWater overflows when cooled below 4^ C .
- CWater overflows either when heated above 4^ C or cooled below 4^ C .
- DWater will not overflow when cooled below 4^ C .
Correct answer
C. Water overflows either when heated above 4^ C or cooled below 4^ C .
Step-by-step solution
The density of water is maximum at 4^ C . As the temperature increases or decreases, the density of water decreases, which increases its volume. Hence, water overflows either when heated about 4^ C or cooled below 4^ C .
