The pH of water at 25°C is 7. When it is heated to 100°C, then what will be the pH of water?

Description : The pH of water at 25°C is 7. When it is heated to 100°C, then what will be the pH of water?

Last Answer : – Remains same

The density of water is 1 g/cc. This is strictly valid at – (1) 0°C (2) 4°C (3) 25°C (4) 100°C

Description : The density of water is 1 g/cc. This is strictly valid at – (1) 0°C (2) 4°C (3) 25°C (4) 100°C

Last Answer : (2) 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 ... 1 g/cm3. Water has the maximum density of 1 g/cm3 only when it is pure water.
