Question

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

Answer 1

Answer:

Why is ice at 273 K more effective in cooling than water at the

same temperature?

Answer:- To achieve the room temperature, the ice at 273 K will absorb latent heat as well as thermal energy. ... 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.

Explanation:

What produces more severe burns, boiling water or steam?

Answer:- Steam causes more severe burns.

Steam causes more severe burns.Steam has more energy than boiling water. It possesses the additional latent heat of vaporization. So, when steam falls on skin and condenses to produce water it gives out 22.5 x 105 J/kg more heat than boiling water at the same temperature.
