| Q. |
Steam at 100°C causes more severe burns than water at 100° C because – |
| A. | steam has no specific heat capacity |
| B. | steam has latent heat of vaporization |
| C. | water has no specific heat capacity |
| D. | water has latent heat of fusion |
| Answer» B. steam has latent heat of vaporization | |
|
Explanation: It is because steam releases its latent heat as it condenses, which is substantial. The heat of vaporization of steam is over 2000 J per gram. And when it releases that it's then 100 degree water, the same as boiling water. |
