Question

Steam causes more sevior burn than boiling water give reason

Answer 1

Boiling water contains only a specific amount of heat energy required for it to boil. However, as steam is formed from boiling water, it contains the heat energy of boiling water, along with the latent heat of vaporization. Hence, as steam has moreheat energy, it can cause more severe burns than boiling water.



Hope it's help you

Answer 2

Phase changes require a lot more energy than just a temperature change. The energy required for water to go from a liquid to a gas is called the heat of vaporization. When steam(water in the gas phase) hits your skin, a lot of energy will be released as it condenses into a liquid, undergoing a phase change.
