no
Fusion welding is just any welding process which inhibites the phase trasition from solid to liquid and then back to solid state, while electric resistance welding is based on purely ohmic heating of the different parts, this heat will create fusion of the metal. So; Electric resistance welding can be said to be a type of fusion welding, but not the other way around.
molar heat of fusion
Yes, welding of metals typically involves heating and fusion in resistance welding, arc welding, acetylene torch welding. Metallic bonds are formed between the substrate and the weld. The composition of the weld and the substrate around the weld inevitably is different from the material being welded.
They are the same thing. Fusion and solidification both mean the changing of a liquid to a solid.
No. Dry ice is carbon dioxide in the solid state. Regular ice is solid water.
yes
The latent heat of fusion
No. Vapor is a substance in its gaseous state. Ice is water in its solid state.
Water can be a solid, liquid, and gas at the same time. This is due to the varying energies of the molecules while they are in a changing state.
liquid to solid
During a change of state, temperature usually stays the same. When a substance is changing from solid to liquid or liquid to gas, the energy is used to break intermolecular bonds rather than increase the temperature. This is known as the latent heat of fusion or vaporization.
When changing from a solid to a liquid, melting, the heat absorbed is called the heat of fusion. When the reverse takes place, freezing, it is called the heat of solidification. For a single substance they are the same.
