Question

ice at 0°c and water at 0°c which is more dangerous give the reason​

Answer 1

Explanation:

water is more dangerous because ice starts melting at 0° C and it becomes water and water starts freezing at 0°C so it becomes more hard and dangerous .

hope it helps

thanks

Answer 2

Water and Ice are of different phase. Water being in liquid and Ice being in solid.  Water at 0°C in liquid state has intermolecular forces weaker than that of Ice at 0°C and that results in liquid state of water.

To convert Water at 0°C to Ice at 0°C, latent heat of fusion comes into play(due to phase change). For water, Latent heat of fusion is 330 joules per gram.

Thus when 330 joules of heat energy is supplied to Ice( 1 gram) at 0°C, it converts into Water(1 gram) at 0°C.This heat energy transfer would obviously lead to some temperature difference.

As a result, we find 0°C Ice is cooler than 0°C Water so Ice is more dangerous.
