Answer

Steam at $100^{\circ}C$ has higher thermal energy than water at $100^{\circ}C$.

Work Step by Step

When steam contacts the cooler skin and condenses, it releases a large amount of energy before turning into water at $100^{\circ}C$. It boils down to the fact that steam at $100^{\circ}C$ has more thermal energy than water at the same temperature, because of water’s large latent heat of vaporization.
