More serious burn are caused by steam at 100c than water at same temperature , because in steam the kinetic energy is more as compared to the water ot same temperature. More kinetic energy means more heat.

Here's your answer...
The specific latent heat of vaporisation of water is 2268 J/g, while the specific heat capacity of water is 4.2 J/g°C.
When 1 g of water at 100°C touches a part of your body, it will release 4.2 J to cool down to 99°C.
But when 1 g of steam at 100°C touches a part of your body, it will release 2268 J to condense to water at 100°C, and then that water will also release 4.2 J to cool down to 99°C.
Since steam releases a lot more heat than water at the same temperature, it cause more serious burns.
