Question

wt is the melting point of ice? why is ice more effective than water in 273k? what is the boiling point of ice?

Answer 1

→ Melting point of ice and freezing point of water, both are same, that is, 0° C or 273.15 K (Rounded off as 273 K

→ Ice is more effective than water at 273 K because water absorbs heat only for evaporation, whereas ice absorbs heat for evaporation as well as the latent heat of fusion. Since ice absorbs more heat, it is effective than water.

→ Boiling point of water is 100° C or 373 K. Freezing point of water is 0°C or 273K.

Answer 2

1)0°c ice starts melting .2) at 273k has more energy as compared to ice at 273k ,since ice can easily absorb energy from surrounding in the from of latent heat to form water whereas water has no such privilege hence ice is more effective in cooling than water at same temperature. 3)100°c is it's boiling point.

{Hope this hlps u out.}
