Question

explain why ice at zero degree centigrade has greater cooling effect than water at 0 degree Celsius

Answer 1

hey dear here is ur answer





 Both ice and water at 0°C cool down other bodies by extracting heat from them. However, when you supply heat to water, it's temperature rises, but in the case of ice, it first melts, and then the temperature of the formed water rises.

Therefore, even if both the ice and the water end up as water finally, the ice extracts an extra amount of heat from the body to be cooled, given by-

ΔH=Lf×MΔH=Lf×M

Where LfLfis the latent heat of fusion of ice, and M is the mass of ice.

hope it helps you dear

Answer 2

❤️❤️ please follow me

To answer your question in brief it's because of latent haet of fusion i.e., ice absorbs more heat than water when it melts (to loosen strong hydrogen bonds) and thus it has greater cooling effect than water at 0°C. ... Water will freeze at zero degree Celsius…means liquid water converted into solid state..❤️❤️❤️
