100 degree Celsius steam contains substantially more energy (and therefore more potential to harm a person's skin) than liquid water at 100 degrees Celsius since the steam has all of the heat the liquid water has PLUS the energy that was required to vaporize the liquid water.
Yes, because steam must lose energy to convert into a liquid when it condenses on your skin. This is in addition to the heat released by the temperature change in the water when it touches your skin, which would be the only source of heat for a liquid burn.
Since the enthalpy of the vapor phase is higher than the enthalpy for the liquid phase of water, steam contains more heat which is then released (exothermic reaction) when it condenses, causing a more severe burn than liquid water alone.
