HEATING THINGS! Peace out. :)
This energy is the enthalpy of fusion (or latent heat of fusion).
Light, and thermal(heat) energy is needed.
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
Heat energy is needed to melt a solid because it increases the kinetic energy of the particles, causing them to break free from their fixed positions in the solid structure. The heat energy required to melt a solid is called "latent heat of fusion."
The energy needed to change a material from solid to liquid is called the heat of fusion or melting point. This energy is required to overcome the intermolecular forces holding the solid together so that it can transition into a liquid state. The amount of energy needed varies depending on the specific material.
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.
heat & electric energy !
presence of heat energy
The answer is SPECIFIC HEAT!
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
The energy needed to melt iron typically comes from heating the iron to its melting point, which requires input of heat energy. This heat energy can be created by burning fuels, using electric resistance, or other heat sources that can raise the temperature of the iron to the point where it transitions from a solid to a liquid state.
