When the pressure on water is increased the boiling temperature of water as compared to `100^(@)C` will be

When water temperature is increased

At 25^(@)C the pH of water is 7. When temperature of water is increased to 70^(@)C than pH of water and nature of water is

What is the vapour pressure of pure water at 100^(@)C temperature ?

At higher altitudes , water boils at temperature lt 100^(@)C because :

Does the temperature change when boiling water at '100^@'C changes to water vapour at '100^@'C ?
