Under what. Condition heat can given to a substances without raising its temperature
the energy that goes into changing a substance from a solid to a liquid (melting) is called the latent heat of fusion.
Heat energy causes matter to melt. The energy breaks bonds in the matter making looser constructions of the material.
A physical change is one where no new substance is produced. Melting is an example of a physical change. When you melt iron, you get liquid iron, it's still the same chemical substance. If you melt copper, you get liquid copper, not liquid iron.
No. The second law still determines if a process will take place spontaneously. The first law does not say that if you drop a block of hot iron into a water bath that the iron can't absorb enough energy from the water to melt it while freezing the water as long as the energy absorbed by the iron matches the energy lost by the water. HOWEVER, the second law tells us this won't happen.
The energy comes from the heat to melt the iron
Iodine sublimes - it does not melt
Iron ore can be melted by fire, or by focused sunlight.
687
This energy is the enthalpy of fusion (or latent heat of fusion).
Energy is required in the melting process because high is needed to melt something
which chemical is used to melt the iron
What are L's? And what's the heat capacity?
The necessary heat is 9,22 joules.
No. The only thing that can actually melt iron is high temperatures.
Not that i know of but you could use a massive force of positive energy to melt the iron in a few seconds.
When you add heat to an iron nail it will get hot. If enough heat energy is added the nail could melt.
