The pH of neutral water at $25°\mathrm{C}$ is 7.0. As the temperature increases, ionisation of water increases. However, the concentration of H+ ions and OH- ions is equal. The pH of pure water at $60°\mathrm{C}$ is:

1. Equal to 7.0

2. Greater than 7.0

3. Less than 7.0

4. Equal to zero

HINT:  With increase in temperature Kw increases.
The pH of neutral water at $25°\mathrm{C}$ is 7.0.
At
and ${\mathrm{K}}_{\mathrm{w}}=\left[{\mathrm{H}}^{+}\right]\left[{\mathrm{OH}}^{-}\right]={10}^{-14}$
On heating, Kw increases, i.e., $\left[{\mathrm{H}}^{+}\right]\left[{\mathrm{OH}}^{-}\right]>{10}^{-14}$
As
or, $\left[{\mathrm{H}}^{+}\right]>{10}^{-7}\mathrm{M}$
With rise in temperature, pH of pure water decreases and it become less than 7 at $60°\mathrm{C}$.
