Compared to a burn due to water at $100°C$, a burn due to steam at $100°C$ is

✓
More dangerous
B
Less dangerous
C
Equally dangerous
D
None of these

✓

Answer

Correct option: A.

More dangerous

a
(a) Steam at $100°C$ contains extra $540$ calorie/gm energy as compare to water at $100°C.$

So it’s more dangerous to burn with steam then water.
