Once the melting point is reached, there is no further increase in temperature until
all of the copper has melted. Discuss what happens to the energy of the copper
atoms before and during the melting process.
Idea that whilst copper is being heated to melting point, energy supplied
is (mainly) transformed into K.E. of atoms/molecules
At melting point:
no change in K.E. of atoms/molecules OR energy supplied is
transformed into P.E. of atoms/molecules
