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.

The heat required to melt ice at its melting point is known as the heat of fusion. For ice, the heat of fusion is 334 Joules/gram. Therefore, to calculate the total heat required, you would multiply the heat of fusion by the mass of the ice being melted (99.5 grams in this case).

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

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.

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.

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

Is it true that it takes a lot of heat to melt a substance with a low melting point?

No, substances with low melting points require less heat to melt compared to those with high melting points. This is because low melting point substances have weaker intermolecular forces holding their particles together, so they can be easily broken with less energy input.


How much heat is necessary to vaporize 500 grams of ice at its freezing point?

The heat required to vaporize 500 grams of ice at its freezing point is the sum of the heat required to raise the temperature of the ice to its melting point, the heat of fusion to melt the ice, the heat required to raise the temperature of water to its boiling point, and finally the heat of vaporization to vaporize the water. The specific heat capacity of ice, heat of fusion of ice, specific heat capacity of water, and heat of vaporization of water are all needed to perform the calculations.


What is heat of fusion of water to melt ice cube?

The heat of fusion of water, which is the amount of heat energy required to melt one gram of ice at its melting point, is approximately 334 joules per gram. This means that to melt an ice cube, the ice must absorb 334 joules of heat energy per gram to transition from a solid to a liquid state.


Does potassium iodide melt easily when heated?

Potassium iodide has a high melting point of 681°C (1258°F), so it requires significant heat to melt.


Does cans melt?

Cans are made of metal, so they have a high melting point and require very high temperatures to melt. The melting point of aluminum cans is around 660 degrees Celsius (1,220 degrees Fahrenheit), so it would require a very intense heat source to melt them.

How much heat is required to melt 68.5 g of ice at its melting point?

The heat required to melt ice at its melting point is known as the heat of fusion, which is 334 J/g. Therefore, the heat needed to melt 68.5 g of ice is 68.5 g x 334 J/g = 22,939 J.


What is the measurement of how much heat energy is required for a substance to melt?

The measurement of how much heat energy is required for a substance to melt is called the heat of fusion. It is the amount of energy required to change a substance from a solid to a liquid at its melting point.


What is the energy required to melt a solid at its melting point?

The energy required to melt a solid at its melting point is known as the heat of fusion. This energy is used to break the bonds between the solid particles so they can move freely as a liquid. The amount of energy needed varies depending on the substance.


The heat needed to melt one gram of a solid at its melting point is what?

The heat needed to melt one gram of a solid at its melting point is called the heat of fusion.


Is it true that it takes a lot of heat to melt a substance with a low melting point?

No, substances with low melting points require less heat to melt compared to those with high melting points. This is because low melting point substances have weaker intermolecular forces holding their particles together, so they can be easily broken with less energy input.


How many joules of energy are needed to melt 54-grams of ice at its melting point?

The specific heat capacity of ice is 2.09 J/g°C and the heat of fusion for ice is 334 J/g. To melt the ice at its melting point, we need to calculate the energy required to raise the temperature of the ice from 0°C to its melting point and then to melt it. The total energy needed would be the sum of the energy required to heat the ice and the energy needed to melt it.


What is required to cause something to melt?

Melting is a change of state of a substance caused by an increase in thermal energy, so heat is required to melt a substance.


How much heat do you need to melt metal?

The amount of heat required to melt metal depends on the type of metal and its specific melting point. For example, common metals like aluminum and copper have lower melting points compared to metals like titanium and tungsten. Generally, the heat needed to melt metal can range from a few hundred degrees Celsius to over 3000 degrees Celsius.


How many BTU does it take to melt 60lbs of lead?

To melt 60 lbs of lead, approximately 25,200 BTU of heat energy is required. Lead has a melting point of 621.5°F and a specific heat capacity of 0.031 BTU/lb°F. Multiplying these values gives the total heat energy needed for melting.


The amount of heat needed to melt one kilogram of a substance?

The amount of heat required to melt one kilogram of a substance is known as the heat of fusion or the latent heat of fusion. It represents the energy needed to change a solid into a liquid at its melting point without a change in temperature.


Why is heat energy needed to melt a solid. What is this heat energy called?

Heat energy is needed to melt a solid because it provides the molecules in the solid with enough kinetic energy to overcome the forces holding them in a rigid structure. The specific heat energy required to melt a solid at its melting point is called the latent heat of fusion.


How do you calculate the current required to melt 14 gauge wire insulation?

To calculate the current required to melt 14 gauge wire insulation, you need to know the specific heat capacity and melting point of the insulation material. You then use the formula Q = mcΔT to calculate the heat energy required to melt the insulation, where Q is the heat energy, m is the mass of the insulation, c is the specific heat capacity, and ΔT is the temperature increase needed to reach the melting point. The current can be estimated using the formula I = Q / t, where I is the current, Q is the heat energy calculated earlier, and t is the time over which the heat is applied.
