⭐ IT IS ON ACCOUNT OF HIGH SPECIFIC LATENT HEAT OF VAPORIZATION THAT STEAM CAUSES FAR MORE SERIOUS BURNS THAN WATER AT 100°C.

⭐ THE ENERGY REQUIRED TO CHANGE WATER INTO ITS VAPOUR AT ITS BOILING POINT WITHOUT ANY CHANGE IN TEMPERATURE IS CALLED THE LATENT HEAT OF VAPORIZATION OF WATER.

⭐ IT'S SPECIFIC VALUE IS 2268 J/g or 540 Cal/g.
