| Q. |
The density of water is 1 g/cc. This is strictly valid at – |
| A. | 0°C |
| B. | 4°C |
| C. | 25°C |
| D. | 100°C |
| Answer» B. 4°C | |
|
Explanation: Water never has an absolute density because its density varies with temperature. Water has its maximum density of 1 g/cm3 at 4 degrees Celsius. When the temperature changes from either greater or less than 4 degrees, the density will become less than 1 g/cm3. Water has the maximum density of 1 g/cm3 only when it is pure water. |
