Question
Water is boiling and is getting converted to steam in a pot. Steam causes more intense heat burns as compared to boiling water when one comes in contact with them. What is the reason behind it?
- Steam has extra latent heat as compared to boiling water.
- Steam is at a greater temperature than water.
- Steam is at a lesser temperature than water.
- Both 1 and 2
Hint:
- It has more energy and hence causes more severe burns.
The correct answer is: Steam has extra latent heat as compared to boiling water.
- Steam has more latent heat (vaporization) than boiling water.
- It has more energy and hence causes more severe burns.
- When water absorbs energy at 100 degrees Celsius it gets converted to vapor without the increase in temperature.
