How much heat is required to melt 99.5 of ice at its melting point?

Answer 1

The enthalpy of liquid water at 0 °C and 1.01325 bar is 0.06 kJ/kg (relative to liquid water at the triple point). The enthalpy of liquid water at 100 °C and 1.01325 bar is 419.06 kJ/kg (relative to liquid water at the triple point). Consequently, 419 kJ/kg are required to raise melted ice to 100 °C.

Answer 2

it melts at zero (for pure water) and also freezes at zero, basically, it needs 80 calories to melt every gram of water, these aren't the kind of calories you see on the Nutrition Facts, because every Calorie there is actually 1000 calories. (notice how one is lower case and the other upper)

yes its true

Answer 3

Ice melts at 0 degrees Celsius or 32 degrees Fahrenheit.

Answer 4

well let's see... water boils at 100 C... so if ice is in an environment that is 100C, then yes. i do believe so. correct me if I'm wrong.

Answer 5

At zero, 0, degrees Celsius frozen water starts to melt as it is heated. It stays at that temp until all of the ice is melted.

Answer 6

energy needed to melt 100 grams of ice into water=mass of ice x latent heat of fusion(80 cal/gm)=100 x 80

=8000 calories

hence energy required is 8000 calories

Answer 7

Ice become a liquid.

Answer 8

33.2kJ
