Question

Which of the following produces more servere burns? 

Solution

Correct option is

Steam

Internal energy of steam at 100oC is more than that of water at 100oC. When steam releases heat, it first converts into water at 100oC and then water starts cooling. Hence, heat released by steam at 100oC > heat released by water at 100oC.
