Question

Which will cause a more severe burn, steam or boiling water at the same temperature?

• A. Steam
• B. Boiling water
• C. Both of them will have the same intensity of burning
• D. Both of them will not cause any sense of burning

Answer 1

The correct option is A

Steam

When we heat water initially from room temperature, the temperature of the water rises. Once water starts boiling its temperature remains constant. All the heat supplied is utilised for the change of state.

All the excess heat supplied will be contained in steam at the same temperature. Hence, steam will cause a more severe burn than boiling water.
