Question

7. Why is ice at 273 K more effective in cooling than water at the
same temperature?
What produces more severe burns, boiling water or steam?​

Answer 1

Answer:

Water at a temperature of 273 K would just absorb heat energy to achieve room temperature. Thus, water at 273 K will absorb less environmental heat energy than ice at 273 K. Therefore ice at 273 K more effective in cooling than water at the same temperature.

Answer 2

Answer:

Ice at 273K is more effective in cooling than water at the same temperature as cie takes latent heat from the substances for melting and hence cools the substances more effectively than water at the same temperature.

Steam produces more severe burns than boiling water even though both are at 100oC because steam contains more heat, in the form of latent heat, than boiling water.
