Question

Compared to a burn due to water at ${100}^{\circ }C,$ a burn due to steam at ${100}^{\circ }C,$ is _______.

• A. More dangerous
• B. Less dangerous
• C. Equally dangerous
• D. None of these

Answer 1

The correct option is A More dangerous

Steam will produce more severe burns than boiling water because steam has more heat energy than water due to its latent heat of vaporization i.e at ${100}^{\circ }C,$ it contains extra 540 calorie/gm energy as compare to water at ${100}^{\circ }C.$ So it's more dangerous to burn with steam than water.
