For the same mass of steam and boiling water, why is a jet of steam more dangerous than boiling water?

The steam has received an extra 540 cal/g (2,260J/g or 970 Btus/lb) of Latent Heat energy above the boiling point of water in order to become steam.
This heat has to be removed by whatever is in the path of the steam jet before it condenses to the same temperature of boiling water. The steam is much more dangerous than boiling water.

1 g of steam gives about 500 calories of heat before condensing and its temperature remains 100 degrees till then. 1 g of boiling water loses 1 degree centigrade with every calories of heat lost by it. Hence when it loses 70 to 80 calories its temperature falls to room temperature. This is the reason that steam is more dangerous than boiling water.

In other words, while boiling water is limited to 100C at 1 atmosphere, steam has the ability to reach much much higher temperatures which can do great amounts of harm to the skin and flesh!!

Steam,in form of vapour,contains LATENT HEAT.Its value is 2268 J/gram.Steam release this amount of energy to condense to water at 100 degress celsius.Hence steam produces more burning effect
