Question

Among the given options, causes most severe burns.

• A. cold water
• B. boiling water
• C. steam

Answer 1

The correct option is C steam

If we start heating pure water, we will notice that at its boiling point, i.e., 100°C, there is no change in thermometer. This is because the boiling water molecules use that energy to overcome intermolecular attractions and convert into steam.

When the steam comes in contact with our skin, it transfers this 'additional heat energy' present in it. Thus, steam causes the most severe burns.
