Where does the energy needed to melt the iron come from?
The energy comes from the heat to melt the iron
How much energy is needed to melt 25.4grams of l2?
Iodine sublimes - it does not melt
How much energy is needed to melt 254 grams of l2?
This is a trick question because "I2" is the chemical symbol for MOLECULAR iodine (your question did not say melt Iodine, it said melt I2).Only gaseous iodine is composed of I2 molecules and as it is a gas it CAN NOT melt.
How much energy is needed to melt 5 grams of ice?
The unit for the heat of vaporization is J/g or Joules per gram of material. The amount of energy required = mass * heat of vaporization = 5.0 g * 5.0 J/g = 25.0 J (Q.E.D.)
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
How much energy is needed to melt 4.24 grams of Pd?
687
How much energy is needed to melt 25.4 grams of L's?
What are L's? And what's the heat capacity?
Where does the energy needed to melt the iron come from?
The energy comes from the heat to melt the iron
How is the Hfusion used to calculate the energy needed to melt a mass of solid?
Grams solid mol/g Hfusion
How much energy is needed to melt 25.4grams of l2?
Iodine sublimes - it does not melt
How many joules of energy are needed to melt 54-grams of ice at its melting point?
The specific latent heat/ latent heat of fusion of ice is 333.55 J/gtherefore by using the equation E=mLE = 54 * 333.55= 18011.7 JTherefore the energy needed to melt 54 grams of ice at its melting point which is keeping it at 0 degrees Celsius is 18011.7 Joules.
Why is heat energy needed to melt a solid what is this heat energy called?
This energy is the enthalpy of fusion (or latent heat of fusion).
How is the Hfusion used to calculate the needed to melt the mass of a solid?
Grams solid mol/g Hfusion
How much energy is gained by 3 grams of ice when it changes to water?
No energy is gained. On the contrary, energy is required to make ice melt.
How much energy is needed to melt 1 metric ton of iron?
1 GAJILLION
Why is energy required for the melting or boiling process?
Energy is required in the melting process because high is needed to melt something
How much energy is needed to melt 254 grams of l2?
