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
Why does it take more heat to boil a substance than to melt it?
The energy required to completely separate the molecules in a liquid and convert them to a gas (boiling), is greater than the energy needed to completely separate the molecules in a solid and convert them to a liquid (melting).
How many kJ of energy are required to melt 30.7 g of ice The heat of fusion of water is 6.02 kJmol. The temperature remains constant at 0 and degC. kJ?
10,267 kJ are needed
Is more energy used to melt ice or freeze water?
The energy required is the same. It is the energy required to rearrange the molecules from one state to another.

How much energy is needed to melt 4.24 grams of Pd?
687
Why energy is needed to melt ice and how this is explained by the structures of ice and water?
Because the ice structure is made up of frozen water molecules, which are blown by fairies creating heat which makes the ice melt like butter in a dragons mouth.
How much energy in kJ is needed to melt 183.3 g of water at 0 C?
Melting of 183,3 g ice need 61,14 kJ.
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).
Can moles melt ice?
no they cant
Why does it take more heat to boil a substance than to melt it?

The heat of fusion for water is the amount of energy that must be absorbed for water to what?
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
What makes water melt faster?
Water doesn't melt, it vaporizes and becomes a gas. The energy from heat melts or vaporizes all matter.
