compared to burn due to air at `100^(@)` a burn due to steam at `100^(@)C` is

Options

A. more dangerous
B. less dangerous
C. equally dangerous
D. none of the above

Answer

To solve the question, "Compared to a burn due to air at 100°C, a burn due to steam at 100°C is?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Context**:
- We are comparing burns caused by air and steam, both at the same temperature of 100°C.

2. **Properties of Air and Steam**:
- Air at 100°C is simply hot air, which can cause burns but has a certain heat capacity.
- Steam at 100°C is water in its gaseous state, which has undergone a phase change from liquid to gas.

3. **Latent Heat of Vaporization**:
- When water is converted to steam, it requires energy known as the latent heat of vaporization. This energy is absorbed by the water to change its state without changing its temperature.

4. **Heat Energy Comparison**:
- At 100°C, steam contains not only the thermal energy associated with its temperature but also the additional energy from the latent heat of vaporization.
- Therefore, steam at 100°C has more total heat energy compared to air at the same temperature.

5. **Conclusion**:
- Since steam has more heat energy, it can cause more severe burns compared to air at 100°C.
- Thus, a burn due to steam at 100°C is **more dangerous** than a burn due to air at 100°C.

### Final Answer:
A burn due to steam at 100°C is **more dangerous** compared to a burn due to air at 100°C.
