(N/A) The temperature of both boiling water and steam is $100\,^{\circ}\text{C}$.
However,steam causes more severe burns than boiling water because it contains additional energy in the form of latent heat of vaporisation.
When steam condenses into water,it releases this extra latent heat,which is why the steam feels hotter and causes more intense heat sensation.
