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

Does the temperature change continuously ?

Compared to a burn due to water at 100^@C , a burn due to steam at 100^@C is

When does water change into ice and then into vapour?

As the water at boiling point changes to vapour its temperature -

If water vapour is assumed to be a perfect gas, molar enthalpy change for vapouration of 1 mole of water at 1 bar and 100^(@)C is 41 kJ mol^(-1) . Calculate the internal energy change when a) 1 mol of water is vapourised at 1 bar and 100^(@)C b) 1 mol of water liquid is converted into ice.

The change of water into water vapour is called -
